Energy-Efficient Data Forwarding Strategies for Linear Wireless Sensor Network
Bongsue Suh, Taejoon Kim · 한국정보기술학회논문지 · 2011
For the linear wireless sensor networks, the sophisticated calculation or management policies of the existing data forwarding algorithms based on the hierarchical structure can be the redundancies that waste the energy of sensor nodes. In this paper, we propose hybrid data forwarding algorithms in which each node respectively has one of two possible forwarding scheme, single hop forwarding and multi-hop forwarding. The determination depends on the distribution of remaining energy levels of every sensor nodes over the network. The mathematical analysis and the numerical results show that the proposed scheme significantly increases network lifetime compared to strategies with the single hop or multi-hop forwarding only. The proposed schemes also show the better performance in remaining energy distribution of sensor nodes after the network’s life.
