DEAR-2: An Energy-Aware Routing Protocol with Guaranteed Delivery in Wireless Ad-hoc Networks

Nodes can connect with each other to form a self-organizing, infrastructure-less, wireless ad-hoc network, in which every node performs the actions of both host and router. The demand for wireless ad-hoc networks is growing because of their simple and quick installation. However, the limited power of nodes and continuously changing topologies of wireless networks adversely affect the performance of wireless ad-hoc networks. A major problem is maximizing the lifetime of wireless networks while ensuring that packets are delivered to their destinations. Much research has been published on the routing protocols of wireless ad-hoc networks, but most of the algorithms focus on a single performance metric of wireless networks. In this chapter, we propose a routing protocol referred to as DEAR-2 for a heterogeneous wireless ad-hoc network. We have embedded the energy and device type awareness features of the Device and Energy Aware Routing (DEAR) routing algorithm in the face routing algorithm, which focuses only on guaranteed delivery.
