Interference-Aware Transmission Power Control for Wireless Sensor Networks

Executive Summary

Maintaining the lowest possible transmission power in the Wireless Sensor Networks (WSNs) is vulnerable to the interference fluctuations because of the bad signal-to-Interference-Plus-Noise-Ratio (SINR). The previous Transmission Power Control (TPC) algorithms do not consider much for the interferences from other 2.4 GHz devices, which can cause significant performance degradations in real world deployments. This paper proposes the Interference-aware Transmission Power Control (I-TPC) algorithm for WSNs. In the proposed algorithm, each node dynamically adjusts the transmission power and the received signal strength (RSS) target, hence the appropriate SINR is provided even when the Wireless LAN (WLAN) interferences become strong.
