Abstract

The area of Wireless Sensor Network (WSN) is covered with considerable range of problems, where majority of research attempts were carried out to enhance the network lifetime of WSN. But very few of the studies have proved successful. This manuscript discusses about a structure for optimizing routing and load balancing that uses standard radio and energy model to perform energy optimization by introducing a novel routing agent. The routing agent is built within aggregator node and base station to perform self motivated reconfiguration in case of energy depletion. Compared with standard LEACH algorithm, the proposed technique has better energy efficiency within optimal data aggregation duration.

Abstract

Several routing protocols have been proposed in recent years for possible deployment of Mobile Ad hoc Networks (MANETs) in military, government and commercial applications. Secure ad hoc networks are expected to meet five security requirements: confidentiality, integrity, authentication, non-repudiation and availability. Routing Algorithm that integrates security and performance requirements are considered to be more advantage. The SRAC protocol optimizes a combined objective function of security and performance parameters. However, the destination wait- time for decision on route selection and TrustworthinessQoS index calculation at each node add up for delay. The use of two different routes and synchronization in the packets results with additional overhead. In this paper, an effective solution that overcomes the cons of SRAC is proposed with same security and better QoS can be achieved.

Abstract

Steganography is derived from the Greek word steganos which literally means “Covered” and graphy means “Writing”, i.e. covered writing. Steganography refers to the science of “invisible” communication. For hiding secret information in various file formats, there exists a large variety of steganographic techniques some are more complex than others and all of them have respective strong and weak points. The Least Significant Bit (LSB) embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file. This technique can be used for hiding images in 24-Bit, 8-Bit, Gray scale format. This paper explains the LSB Embedding technique and Presents the evaluation for various file formats.
