Analysis of Modified Cooperative Transmission Routing Protocol in Manet


K. Vanisree and V.S.K. Reddy

The major problems faced by wireless communication in real time environment are that of interference and un-reliable communication links. A lot of research work has been done to overcome this using various techniques. Two of the techniques that help in reducing interference and communication link failures are co-operative communication and transmission side diversity in the network. In this work, we propose a new type of protocol that proactively selects a group of forwarding nodes that work co-operatively in forwarding the packet towards the destination. Multiple nodes are selected so as to co-ordinate their transmission to achieve transmission side diversity. In this network nodes are equipped with Omni-directional antenna to achieve transmission side diversity. We have also proposed a new technique to find the optimum route between the source and destination that incurs the minimum cost in terms of energy, no. of hops, available bandwidth and outage probability. We have done extensive simulation based studies to verify the proposed techniques achieve average energy savings of about80%in random networks and also find that our technique using Linkcost and outage gives better results in terms of throughput, end-to-end delay and energy consumption than without using Linkcost and outage model

Keywords: Cooperative transmission, energy efficiency, network reliability, outage probability, routing, wireless networks.
