Energy Balance Optimization for Prolonging the Lifetime of Wireless Sensor Network

摘要

A wireless sensor network is comprised of a large number of battery-limited sensor nodes. In a predefined period, sensor nodes get data and transmit data to BS by a fixed construction. In this paper, we introduce a scheme for selecting the construction to prolong the lifetime of wireless sensor network based on energy balance. Further, an optimal math model is proposed for calculating the energy cost of each node in a predefined period. At last examples show that the scheme is feasible.
