Abstract

The objective of this paper is to propose a unique connectivity index, nci which indicates the quality of route when nodes move randomly. The most reliable route is then chosen using GA route selection mechanism. The node mobility model is introduced and shows that there exists upper bound for velocity in order to achieve reliable wireless communication. The nci is then derived based on contraction and expansion model. It is then utilized as one of the fitness variable in our multi objectives GA-based QOS Routing protocol. It has been observed that the performances of our protocol QOSRGA on velocity scenario are better than the BE-DSR routing protocol.
