A Range-based Opportunistic Routing Protocol for Wireless Sensor Networks

摘要

Wireless Sensor network (WSN) can be defined as a collection of battery powered wireless sensor nodes, which can sense events in the environment and share the data gathered from sensing node to a sink node. However, this type of network is seriously constrained by energy supply. Therefore, how to enhance the network lifetime is a prominent and challenging issue. In this context, the choice of the suitable routing protocol is a vital task in the network layer of WSN. This paper describes the EEOR (Energy Efficient Opportunistic Routing), which focuses on the selection of the forwarding list to minimize energy consumption. Then, we define a new strategy of opportunistic routing, denoted ROR (Range-based Opportunistic Routing), which is an improvement of EEOR. Simulation results demonstrate that ROR is the most efficient to minimize the energy and the number of dropped paquets.
