Energy Efficiency Analysis of Adaptive Error Correction in Wireless Sensor Networks
In this paper, we develop an analytical energy efficiency model using adaptive error correction code (AECC) in wireless sensor networks in fading environments. To adapt energy efficiency of sensor node to channel variations, the packet length is tuned at the data link layer. In this model, we consider the error control of Bose-Chaudhuri-Hochquengh (BCH) coding for NC-FSK receiver node using AECC scheme and compare it to one of non-AECC. The analysis is based on Mica2 sensor node where a look-up table of distance vs. adaptive correction code is installed in the node sender. Depending on channel state variation via the ACK feedback, the sender can adjust the adequate BCH code required for the next transmission. The numerical results show that the AECC scheme can significantly improve the energy efficiency for the long link distance and under various packet lengths over Rayleigh fading channel.
Keywords: BCH Coding, Adaptive Coding, Energy Efficiency, Fading Channels, Wireless Sensor networks.
