Abstract
Opportunistic routing (OR) is a new paradigm in routing protocol for wireless sensor network (WSN). The OR has aroused wide concern because it can improve the energy consumption and reliability in wireless sensor networks (WSNs), especially if the most sensor nodes are equipped with a limited norechargeable battery power. In this context, performing optimal routing strategy is a crucial task at the network layer of WSN. In this paper, we focus on minimizing energy consumption and enhance the network lifetime. Indeed, we proposed a new opportunistic routing algorithm called ECS-OR (Energy Candidate Set-opportunistic Routing) that permit to balance energy consumption and extend the lifespan of wireless sensor network. Extensive simulations show that our proposed routing strategy ECS-OR can significantly improve the network performance on energy saving and wireless connectivity in comparison with other existing WSN routing schemes.
