Optimization of Hello messaging scheme in MANET On-demand routing protocols using BFOA
Harpreet Kaur, Jasmeet Singh · 2014
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. We have made both the protocols adaptive and then for optimization BFOA is applied. The proposed scheme reduces the energy consumption and overhead of neighbor discovery processes.
