Optimal energy consumption for wireless sensor networks

Abstract

Due to congenital restriction of sensors, it is always a crucial issue on how to utilize limited energy effectively. We first put forward a network topology construction method, based on energy saving, including the way of forming a cluster and selecting middle heads and cluster heads. We then employed Simulated Annealing method to optimize energy consumption of the whole system. Results show that the proposed method is able to evenly distribute energy consumption among sensors, lengthen the lifetime of each sensor, prolong network lifetime, and increase network transmitted data volume.
