Performance Comparison on Trust Based Power Aware Reliable On Demand Routing Protocol in Mobile Ad Hoc Networks
IOSR Journal of Computer Engineering
A mobile ad hoc network (MANET) is a collection of mobile wireless nodes, which communicate to each other without any centralized administration. Trust and Power consumption is the most challenging task in routing protocol design for Mobile ad hoc networks (MANETs), since the highly dynamic nature of MANET coupled with limited bandwidth and battery power imposes severe restrictions on routing protocols especially on achieving the routing. Furthermore replacing and recharging batteries and
... nodes co-operative are often impossible in significant environments. In this paper, we effort to study the performance of three ondemand routing protocols (AODV, DSR, DYMO) in terms of number of hop counts, number of routes selected, number of RREQ packets, number of RREP packets and power consumption in transmit, received and ideal modes. During route discovery, nodes are more trust to find reliable route for communication and utilizing maximum energy capacity for selection of route. Route based selection of nodes called 'Reliability'. Route request from the source is accepted by a node only if its reliability is high. Otherwise, the route request is discarded. This approach forms a reliable route from source to destination thus increasing network life time, improving power utilization and decreasing number of packet loss during transmission. To solve the above problem here we describe the three on demand routing and it is simulated using QualNet 5.0 simulator. I.

However much or less attention has been paid in making the routing protocol to choose a more reliable route. In critical environments like military operations, data packets are forwarded to destination through reliable intermediate nodes. Hence our work focuses on augmenting the existing on-demand routing protocols and making them reliable. We have used AODV (Ad hoc on-demand distance vector) DSR (Dynamic source routing) and DYMO (Dynamic MANET On-demand) protocol as the base on-demand routing protocol for our model. We have used the means of simulation using QualNet 5.0 simulator to gather data about these routing protocols in order to evaluate their performance   . The rest of this paper is organized as follows: in section II problem formulation and major issues. In section III trust based power aware on demand routing protocols is discussed. In section IV Simulation setup and platform used in this work is discussed. In section V the results of the performance evaluation are thoroughly discussed. Conclusion and future work is given in section VI.
