Optimization of Hello Messaging Scheme in MANET On-Demand Routing Protocol Using PSO
Mobile Ad hoc NETwork (MANET) is an autonomous, self-configuring and infrastructure-less system in which various mobile nodes are connected by wireless links. In MANETs hello messages are periodically exchanged to maintain the connectivity of neighbor nodes. While discovering neighbor nodes, an unnecessary hello message causes the problem of battery drainage in MANET routing protocols like AODV and DYMO. These ad-hoc types of networks are mainly used in the smart phones and origin the problem of energy utilization when neighbor nodes are discovered to maintain the connectivity.
