Location Aware Cluster Based Secured Anonymous Routing for Manet

A MANET is a type of Ad-hoc network that can change locations and configure itself on the fly. The Ad-hoc On Demand Distance Vector (AODV) protocol used for stable route which incorporates nodes with least relative mobility between them and the Public Key Cryptographic method for secured transmission which is used for message authenticity is proposed. The Cluster heads initiate the key generation, keys are distributed from the cluster heads which reduces the overall overhead of the network. The effects of using different transmit powers on the average power consumption and end-to-end network throughput in a wireless ad-hoc environments investigated which helps in reducing the system power consumption, pro-longing the battery life of mobile nodes and improves end-to-end network throughput due to minimizing interference ranges, reduction in the average number of hops to reach a destination, the probability of having isolated clusters, and the average number of transmissions. The protocol dynamically determine an optimal connectivity range by adapting their transmit powers so as to only reach a subset of the nodes in the network. The connectivity range would then be dynamically changed in a distributed manner so as to achieve the near optimal throughput. The work is simulated using Omnet++ 3.3. The simulation results are presented showing that the proposed increases packet delivery ratio, throughput. It also reduces the latency and energy consumption.
