Analyzing the relationship between route stability and calculation methods of routing metrics

A Mobile Ad-hoc Network (MANET) is a non centralized and self configuring network of nodes with a facility of immediate deployment in any part of the world. In these kind of networks, nodes are connected through wireless links with an auxiliary topology and without any pre-existing infrastructure. However due to mobility of nodes and un-centralized control, routes in MANET are unstable in nature. For which range of different routing protocols (AODV, DSR, DSDV, etc) and different routing schemes have been proposed, the major focus of which have been laid in changing routing metric and saving power sources. We changed the route cost calculation method in AODV routing protocol and analyzed it in different routing scenarios through changing number of nodes as well as nodes mobility. Through evaluation of performance comparison it is observed that effectively of a certain routing technique depends on location of nodes as well as their modes whether they are static or mobile.
