Abstract :
To prolong the lifespan of wireless sensor networks, while working with the limited battery life of each sensor node, energy efficiency and energy balance are basic considerations. To achieve balanced energy consumption, non-uniform distribution methods are proposed as a network infrastructure modeling scheme. However, node transmission distance, which has significant relevance with energy efficiency, is not factored into calculations. Based on a previous non-uniform distribution method, we analyze energy consumptions under different corona width, and then derive a distribution model with optimal average transmission distance. Results demonstrate an efficiency increase of 24% compared to networks with unadjusted corona widths, and the lifetime of the network is prolonged.
