Due to the uncertainty in the available spectral resource, there is a need of inimitable challenges in cognitive radio networks. The most common decisive issue is that the performance degradation in cognitive radio ad-hoc networks (CRAHNs) experienced by cognitive users (CUs) due to the variation in the activity of primary users (PUs) in both frequency and space domain, diversity techniques can be represented an efficient way to address this issue. In this paper, we propose a link reliable joint path and spectrum diversity technique by modifying D2CARP with link quality metric such as CETX instead of hop count for effective use of spectrum in CRAHNs, is referred to as Link Reliable Dual Diversity Cognitive Ad-hoc Routing Protocol (LR-D2CARP). Make use of both link reliable path and spectrum diversities, CUs can switch dynamically to different link reliable paths as well as spectrum bands for communicating with each other in the presence of frequency- and space-varying PU activity. The simulation results reveal the effectiveness of our protocol in CRAHNs.Keywords

A MANET is an interconnection of mobile devices by wireless links forming a dynamic topology without much physical network infrastructure such as routers, servers, access points/cables or centralized administration. The multipath routing protocols establish efficient communication within the network by discovering multiple routes between a pair of source and destination in order to have load balancing to satisfy Quality of Service (QoS) requirements. In this paper, the QoS comparison of three multipath routing protocols are carried out in terms of five scenario patterns such as RWM, RPGM, MGM, GMM, and PMM in two different traffic patterns such as CBR and TCP using NS2 and Bonn Motion. The multipath routing protocols AOMDV, OLSR and ZRP have been selected for simulation due to their edges over other protocols in various aspects.Keywords

Conversational real-time applications like VoIP (Voice over IP) and videoconferencing require new challenges in Long-Term Evolution (LTE) networks such as Internet. Quality of video delivered over the Internet has been determined in terms of Quality-of-Service (QoS) and Quality-of-Experience (QoE). QoS includes packet delivery ratio, average end-to-end delay, throughput, routing overhead, etc. QoE is a qualitative measure of videos transmitted over Internet. In this paper, the performance comparison of AODV, OLSR and ZRP are carried out on H.264/MPEG-4 AVC video streaming under both Distributed Coordination Function (DCF) and Enhanced Distributed Coordination Function (EDCF) using NS2.34 and Enhanced EvalVid framework. These protocols have been selected for simulation due to their edges over alternative protocols in numerous aspects.Keywords
