Mathematical Modeling of Routing Protocol Selection for Optimal Performance of MANET

In Mobile Ad-Hoc NETwork (MANET) there are many uncertainties like topological changes, number of nodes, mobility etc. Since the design of routing protocol is carried out by considering a particular environment, no existing routing protocol performs well for all possible environments and requirements. This paper proposes an adaptive protocol selector for MANET which helps in selecting an optimum routing protocol by learning the current network context and user requirement. Here we have chosen DSDV, AODV and DSR protocols for the selection process. We discuss about the design of adaptive protocol selection module and simulated results of Protocol Regression Model (PRM). The PRM predicts the routing protocol performance for the current network context which helps in determining the appropriate protocol for a particular environment.
