Mobile ad hoc networks (MANETs) are a setup of several independent nodes that are capable of transmitting any kind of data by themselves. In MANETs, the node themselves act as routers and the setup can either be single hop or multihop depending on the application. These devices have wide and varied applications; like in military deployment, for network set up in meetings, electronic classrooms etc. As the applications and use of MANETs has increased, it has also become imminent for MANETs to support multimedia transmission, high quality data transmission and also to work efficiently in a congestion scenario. To support these parameters it is necessary to have a robust routing protocol that provides good Quality of Service (QoS) parameters under different conditions. In this paper the authors simulate transmission of multimedia traffic with AODV nthBR routing protocol for a high density MANET setup. AODV nthBR routing protocol is also simulated for a congestion scenario and the results are then compared with the existing routing protocols.Keywords

In this paper, the Mobile Ad Hoc Networks (MANETs) with integrated Primary/Secondary User (PU or SU) traffic has been considered. Nodes in the MANET are equipped with Cognitive Radio Technology (CRT). The blocking probability and dropping probability for SUs are obtained by considering a 3D Markov Chain analytical model. To provide efficient service to PUs, we offer priority of channels, higher priority and lower priority is given to PUs and SUs, respectively. The expressions for blocking probability, dropping probability, throughput and non-completion of SU are established. Sensitivity analysis is carried out to explore the effect of system parameters. It is observed that Ad Hoc network utilized the unused spectrum of the existing legacy systems in an opportunistic manner in addition to using the unlicensed spectrum. The results show an improved performance in terms of blocking probabilities, dropping probabilities of SU and over all throughput of the system.Keywords
