Secured and Stable Routing Protocol For AdHoc Networks

Abstract

The desire to be connected anywhere, anytime and anyhow has led to the development of wireless networks, especially in the area of persistent and omnipresent computing. The Mobile Ad-hoc networks is a collection of two or more nodes with wireless communications and networking capability that communicate with each other without the aid of any centralized administrator. Ad-hoc networks are also called infrastructure less networks as they do not have any fixed topology or infrastructure. Each and every node in the wireless ad-hoc network act as a host or a router or both therefore refined secure and stable routing protocols are needed to safeguard the data against the unauthorized access. The work presented in this thesis is an effort to provide secure and stable ad-hoc routing protocol, termed as Energy Efficient Wireless Path Optimization (EEWPO) newlineThe secure, flexible and robust routing based mechanism has been designed under the proposed model routing scheme for the wireless ad-hoc networks, which is based upon the combination of dynamic route selection based upon genetic programming mechanism and connection integrity assurance algorithm. The new combination is capable of adding the higher level of security for the prevention of the connectivity holes and the fake route injections in the given network. The smart path selection across the multipath network becomes very important in the voice based ad-hoc networks, which requires the dedicated connections for the exchange of the voice data over the ad-hoc channel. The creation of the adaptive ad-hoc network routing solution takes the perfectly layered combination of the genetic programming based routing solution along with the connection integrity assurance model in order to realize the robust ad-hoc routing algorithm. The proposed routing protocol has been verified through various simulation scenarios. newline newline
