Adaptive Scheme for suppressing unnecessary Hello messages used for Neighbor Discovery in MANET routing protocols

Mobile ad-hoc networks are widely used these days as in smart phones but energy efficiency is a major issue when discovering neighbor nodes to maintain connectivity as periodically exchanging hello messages are used for it. Overhead goes high due to neighbor discovery messages in the MANET routing protocols, such as in AODV, DYMO. In an attempt to enhance the scheme, this paper proposes a new approach to solve the problem by reducing unnecessary hello messages. In this paper we consider MANET under random waypoint model and investigated the relationship between the hello interval and event intervals. Finally we evaluate our study through simulations, the proposed scheme reduces the energy consumption and overhead of neighbor discovery processes.
