Abstract:

An efficient node scheduling algorithm can significantly improve both the perceived ability and the energy efficiency for wireless sensor networks.Based on the model analysis of network node power consumption,an energy-efficient adaptive node scheduling algorithm for target tracking (ANSTT) is proposed for wireless sensor network.The algorithm automatically adjusts the working mode of sensor nodes according to the perceived ability on moving target and the relative remaining energy level (RREL) of nodes.Experiment results show that the proposed ANSTT algorithm effectively reduces system energy consumption and prolongs network lifetime while maintaining low detection delay and high target perceived rate.

Key words: wireless sensor networks, node scheduling, target tracking, adaptive, energy-efficient
