AD-HOC Better Costing Dynamic Routing Protocol for Enhancement of Network Lifetime

Mobile ad hoc networks are generally infrastructure-less networks that are self-organizing temporary networks. They do not have a centralized controller. They are applied in diverse sensing and mobility applications. Routing in such networks requires a lot of considerations. Energy efficiency is a challenge in MANETs. This is because since nodes are in motion, they require energy. Energy efficiency in the network is increased by reducing power consumption. This is the primary idea behind this paper. The objective is to enhance the network's lifetime by avoiding the nodes from moving out of the network. We hence propose a novel routing protocol, Ad hoc Better Costing Dynamic (ABCD) protocol, which focuses not just on the residual battery power of the node but also on the energy required to forward the packets through the route. While choosing the path, according to the Mini-max formulation, the path which has the maximum energy among the lowest hop energy is given high preference. The purpose is to avoid using the path with the lowest energy, leading to link breakage. This paper evaluates three routing protocols, Ad hoc On-demand Distance Vector (AODV) routing protocol, Dynamic Source Routing (DSR) protocol and Ad hoc Better Costing Dynamic (ABCD) routing protocol and finds the ABCD protocol to perform better.
