Reliable Data Delivery in Mobile Ad-Hoc Network using Fisheye State Routing

This paper addresses the problem of reliable data distribution in dynamic large scale mobile ad-hoc network, for which existing routing protocols are not suitable. An efficient Position-based Opportunistic Routing (POR) protocol is good in delivering the data in highly dynamic MANETs. But it is affected by the over heading problem and moreover there are no data confidentiality and data security. So we proposed a proactive routing algorithm known as Fish Eye state routing algorithm. This FSR algorithm provides excellent solution for delivering data in highly dynamic ad-hoc networks by updating and communicating nodes and nodes position and delivering data without over heading. Our proposed scheme works well in a large network of high mobility nodes. But still there is some susceptibleness to security threaten i.e., packets dropping by malicious nodes in the network. Our security scheme is proposed to minimize the number of black holes or malicious nodes or selfish nodes in the path to the destination, thus the number of data packets dropping can be minimized, and we secured the FSR protocol with security. In the case of communication hole, a Virtual Destination-based Void Handling (VDVH) scheme is further proposed to work together with FSR. KeywordsFSR, MANET, POR, VDVH
