Mobile Ad-Hoc networks (MANETs) have become very popular for military applications,disaster recovery operations in which the fixed network infrastructure might not be availabledue to wars, natural disasters, and the like. One of the main research challenges in mobile adhoc networks is designing adaptive, scalable and low-cost routing protocols for these highlydynamic environments. In this thesis, we propose a new metric called hop change metric inorder to represent the changes in the network topology due to mobility. Hop change metricrepresents the changes in the number of hops in the routing table. It is believed that thechange in the hop count is a good representative of the mobility. The high number of changein the hop count can be a sign of high mobility. This metric is implemented in two popularand main routing protocols. Hop change metric is firstly employed to the most popular reactiveprotocol AODV (Ad hoc On-Demand Distance Vector Routing).
