Adaptive Emitting Power Control Protocol for Wireless Sensor Networks

Since sensor nodes are energy constrained devices, optimizing the energy efficiency of wireless sensor networks (WSNs) is a key issue. In this paper we present a new, simple and easy to implement protocol to reduce the energy consumption of nodes. The purpose of the proposed algorithm is to monitor the transmission power of sensor nodes while communicating. The algorithm has been studied, analyzed and then implemented on the nodes. The quantitative and qualitative analysis present similar results, and with the proposed solution a reduction of 50% of the energy spent in the transmission process compared with the standard specifications has been achieved.
