The objective of the work is to analyze the impact of weather conditions on different types of MANET routing protocols. The influence of weather on the performances of MANET protocols such as AODV, STAR, RIP and ZRP are compared with and without considering weather conditions. Most of the works are not considering the effect of weather, when analysing the performances of MANET protocols. The simulations are carried out using Qualnet 5.0 with 100 nodes. The mobility model used for simulation is the Random waypoint model, where each node is moving independently to reach the destination with a random velocity. The velocity of each mobile node varies from 10 m/s to 50 m/s with the weather intensity of 1000 deg/m2. The performance metrics such as end to end delay, jitter, through put and packet delivery ratio are analysed and compared. The simulation results reveals that AODV provides better throughput and high packet delivery ratio compared to other protocols under with and without considering weather. STAR protocol yields good performance with respect to end to end delay and jitter under both conditions.Keywords

The wireless mobile network is particularly vulnerable due to its features of open medium, dynamic changing topology, cooperative algorithms, lack of centralized monitoring and management point, and lack of a clear line of defense. The traditional way of protecting mobile networks with firewalls and encryption software is no longer sufficient and effective. New distributed intrusion detection schemes must be designed for wireless mesh mobile networks. In the first phase of the work a static simulation was completed for analyzing load balancing approaches in mobile network. In the second phase of the work we try to devise a method where we put a distributed IDS agent in each node of the wireless mobile network so that each node studies the packet flow in the corresponding mobile network and distributes it to the near by nodes in the mobile network. With this, the nodes will know the details of the packet flow in the entire mobile network using the swarm intelligence technique; thereby it tries to identify the intrusion that happens by various rule mining techniques. Here we implement hierarchical, extensible and flexible detection architecture to thwart such threats. Thus this system will help us detecting and tracking the intrusion at the early level itself with the use of hierarchical model. This will help us to reduce the false positives as well as false negatives, which will give more accuracy in detection and also increasing the quality of service in the mobile network. The overall load balancing characteristic of the network is hence improved.Keywords

An experiment was carried out during Rabi, 2013 at Eastern Block of the Central Farm Unit, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify resistant progenies in BC3F1 population against sorghum downy mildew (SDM) incited by Peronosclerospora sorghi. Sorghum downy mildewis one of the most serious diseases in maize producing areas throughout the world. P. sorghi (SDM) is a factor that limits maize production in several countries of Asia (Rifin, 1983). Therefore, there is a need to develop the new maize cultivars with resistance to SDM in order to enhance the yield. In this present study, experiments were undertaken under vigorous artificial infection conditions in spreader row technique during Rabi, 2013 for characterization of responses of 22 back cross progenies to the SDM; in which 16 progenies were confirmed as phenotypically resistant to sorghum downy mildewviz., UMI 79/936- C1-3-2, UMI 79/936-C1-3-4, UMI 79/936-C1-7-2, UMI 79/936-C1-7-7, UMI 79/936-C1-29-8, UMI 79/936-C1-29-9, UMI 79/ 936-C1-29-13, UMI 79/936-C1-29-23, UMI 79/936-C1-29-35, UMI 79/936-C1-29-36, UMI 79/936-C1-67-3, UMI 79/936-C1-67-12, UMI 79/936-C1-67-25, UMI 79/936-C1-101-12, UMI 79/936-C1-101-13 and UMI 79/936-C1-101-14. Resistant lines will serve as basis material for developing single cross and double cross hybrids for resistance against sorghum downy mildew in maize.Keywords

Retail industry is one of the pillars of Indian economy with its huge opportunities. Retail industry is largest in India, with an employment of around 8% and contributing to over 10% of the country's GDP. The Indian retail industry can be divided into two parts i.e. organized and unorganized sectors. Organized sector retailing refers to trading activities undertaken by licensed retailers i.e. those who are registered for sales tax, income tax etc. These include the corporatebacked hypermarkets and retail chains, and also the privately owned large retail businesses. Unorganized retailing, on the other hand, refers to the traditional formats of low-cost retailing, for example, the local kirana shops, owner manned general stores, paan/beedi shops, convenience stores, hand cart and pavement vendors etc. In the recent past the organized retail sector in India is experiencing its transformation. Customers are preferred to shop at organized retail shops due to increased disposable income, changing life styles and quality of services offered by the retailers. In this view the retailers are concentrating on having better HR policies to satisfy their employees there by satisfying the customers too. But satisfaction of the employees is very difficult as the satisfaction is not only depended on the organizational facilities but demographic profile of the employees as well. Therefore the present study is an attempt to identify factors influencing employee satisfaction and the linkage between the demographic factors and employee satisfaction which will boost the development in the sector.Keywords

Objectives: To design and analyze the performance of CMOS RF Oscillator circuits at low supply voltage. Methods/Statistical Analysis: The Current Mode Logic (CML) based oscillator and LC oscillator is designed for 5GHz WLAN applications. The CML design adopts a DCO topology and the schematic layout is drawn using Microwind 2.7. The performance analysis is carried out using Intel Core2 Duo CPU E7400 @ 2.80 GHz processor. Advanced Design System 9.0 is used to implement schematics for analyzing the performances of proposed LC tank oscillator. Findings: The simulated results show that the tri-state inverter based DCO has 20 to 30% power reduction which is more than other conventional oscillator circuits. The CML inverter based DCO consumed more power than tri-state inverter because it used tail current transistor that provides always the static path from supply to ground. The theoretical phase noise is compared with simulated value of –95.19 dBc/Hz at same offset frequency. Application/Improvements: These designs produce a substantial improvement in performance and may be easily integrated with RF front-end blocks with minimal interface problems.Keywords

The design of low rate Wireless Personal Area Network (WPAN) by IEEE 802.15.4 standard has been developed to support lower data rates and low power consuming application. Zigbee Wireless Sensor Network (WSN) works on the network and application layer in IEEE 802.15.4. Zigbee network can be configured in star, tree or mesh topology. The performance varies from topology to topology. The performance parameters such as network lifetime, energy consumption, throughput, delay in data delivery and sensor field coverage area varies depending on the network topology. In this paper, designing of hybrid topology by using two possible combinations such as star-tree and star-mesh is simulated to verify the communication reliability. This approach is to combine all the benefits of two network model. The parameters such as jitter, delay and throughput are measured for these scenarios. Further, MAC parameters impact such as beacon order (BO) and super frame order (SO) for low power consumption and high channel utilization, has been analysed for star, tree and mesh topology in beacon disable mode and beacon enable mode by varying CBR traffic loads.Keywords

A highly compact and an optimized design of an Inverted L shaped printed monopole antenna with a simple compact ground plane is proposed. To make the designed antenna suitable for implantation it is embedded in FR-4 substrate and is presented. The antenna is designed for dual-band operation at 2.4GHz and 5.2GHz. It is suitable for Wireless Local Area Network (WLAN) applications with return loss (S11) < -10dB. The antenna has two different resonant current paths that support two resonances at 2.44GHz and 5.18GHz (forming an F-shaped structure). The size of the antenna is 32.5mm × 19.6mm × 1.6mm. The antenna design is simulated using the tool Advanced Design System (ADS) 2014. This antenna design has good return loss and radiation characteristics in both the required frequency bands. The radiation pattern obtained from the proposed antenna is an Omni directional radiation pattern in the E and H plane over the frequency ranges 2.4GHz and 5.2GHz.Keywords

The IEEE 802 standard well-known as 802.11 called as Wi-Fi network, 802.15.4 called as ZigBee or sensor network and 802.15.1 called as Bluetooth network. The network such as ZigBee, Bluetooth and Wi-Fi works in 2.4 GHz ISM band. All the above networks works in same ISM band of 2.4 GHz, but the performance of the network varies. The performance of simulation depends upon the coverage area, data rates, and power consumption in each network. The heterogeneous network performances is evaluated with static and mobility model in random and grid node placement by varying the traffic loads of one CBR and with five CBR for each network. The simulation result is compared in terms of jitter, average end to end delay and throughput to analyze the network performance in the 2.4 GHz frequency band. IEEE 802.11 network shows the low jitter and delay value with high throughput compared with sensor network.

The chalcone was synthesized from cyclohexanone and an aromatic aldehyde by aldol condensation reaction, followed by cyclisation with thiourea results in hexahydro quinazoline. The third position is methylated by using methyl iodide, finally the mannich reaction was carried out with five different amines at second position of the hexahydro quinazoline to get five different S-Mannich bases. All the 5 synthesized new compounds were studied for their physiochemical characters. And their structures were confirmed by spectral studies (IR, NMR). These new derivatives were evaluated for analgesic and anti-inflammatory activity.

Mobile Ad-hoc Networks (MANETs) are a special kind of network that organize by itself, and they provide high-quality service despite the cost of routing. In MANET, there exist no option to reach other hosts in a single-hop where it needs multi-hop. Many intermediary hosts relay packets transmitted by the source host before reaching the destination host in a multi-hop situation. The level of energy at each node plays a significant role in MANET. Routes are frequently broken, and new routes are discovered in MANETs because of node mobility. In this paper, Energy-Efficient Perspicacious Ant Colony Optimization Based Routing Protocol (EEPACORP) is proposed to determine the optimum route to transfer the data to reduce energy spent by each node for data transmission. EEPACORP is based on the ant's inherent disposition to seek for food. EEPACORP is inspired from genetic character of ant towards finding its food. Pheromone concentration are modified in EEPACORP to find the most appropriate route. The performance of EEPACORP is analyzed in NS3 using standard network metrics. EEPACORP's studies demonstrate that it reduces delays and energy consumption better than the present routing methods.Keywords

One of the most groundbreaking concepts in wireless networking is the mobile ad hoc network (MANET). It is an ever-shifting network of wireless nodes that may be adaptively and indiscriminately positioned, with the interconnections between nodes constantly changing. Defense networks, in particular, are becoming more prominent, and it is the goal and passion of technology to update and improve its components. There is a significant rise in transmission costs due to the high energy usage. Routing protocols have a critical role in reducing energy utilization. Weak routing protocol leads to exhaustive energy consumption, packet delay and packet loss. Ingenious Grey Wolf Optimization-based Routing Protocol (IGWORP) is proposed in this paper to discover the most efficient path to a destination and reduce the amount of delay and energy spent. IGWORP mirrors the natural tendencies of the grey wolf towards foraging for its prey. IGWORP looks for a global route rather than assembling many local routes. Encircling and hunting characteristics of wolves are used in IGWORP to discover and utilize the route for data transmission. Standard network metrics are used in NS3 to evaluate IGWORP's performance. The findings of IGWORP demonstrate that it reduces delays and energy consumption better than the current routing methods.Keywords

In mobile ad hoc networks, path stability estimation is a major difficulty because of connection failures that affect network nodes' mobility. In MANETs, path stability estimates must be based on a unified model that accounts for network node mobility and topology-triggered reactive path distribution statistics between surrounding nodes. It is possible to increase the collaboration between nodes in MANET by implementing an effective, trustworthy cum optimization-based routing protocol. This paper proposes the Ambient Intelligence-based Fish Swarm Optimization Routing Protocol (AIFSORP) to find the most efficient route to a destination and decrease the time and energy required. AIFSORP is designed to mimic the ant's innate instincts to forage its food. In AIFSORP, nodes quickly notify their neighbors when they discover a possible route to their target. Only when the route meets the threshold criterion is it picked for data transmission and shared with neighboring nodes. Optimization plays a significant part in AIFSORP towards determining the best route to the destination. AIFSORP's performance is evaluated using NS3s with standard network metrics. Compared to current routing systems, AIFSORP decreases delays and energy usage more effectively.Keywords
