SDFS: Secured Data Forwarding with Minimum Selfishness and Message Overhead in Mobile Wireless Network

MANET (Mobile Ad Hoc Network) consists of mobile nodes having no fixed infrastructure. These networks have dynamic topology and all the nodes are in general autonomous. Normally network comprises of selfish individuals that are not willing to forward the packets but wants to forward their own messages. In ad hoc network throughput increases when all available nodes are used for routing and forwarding. So instead of avoiding selfish nodes from the routing path the network can effectively utilize all the existing nodes. In this research, selfishness of the nodes is studied and better security methods are proposed to ensure reliable delivery of messages. Simulation results shows that the proposed system ensures less message overhead, memory and time. Also it tries to improve the packet delivery ratio.
