Exploring Possibilities for RSS-Adaptive Power Control in MICA2-based Wireless Sensor Networks

Abstract

Careful control of power transmission levels can play an important role in prolonging the lifetime of a node in a wireless sensor network. Thus in designing efficient wireless sensor networks protocols serious consideration should be given to this factor. This paper investigates the relationship between power transmission levels and received signal strength and packet reception rates, when MICA2 motes are used. The measurement-based approach obtains real-world performance data of MICA2 mote communications as power transmission levels are varied. The results presented here may therefore be of use in the design of power control algorithms in new communication protocols for the MICA2
