Adaptive error control in Wireless Sensor Networks

From the empirical observation that packet errors are influenced by environment condition, we propose an adaptive FEC (forward error correction) mechanism that chooses appropriate error-correction code according to the packet error rate in wireless sensor networks (WSNs). We show that our adaptive FEC (ADL-FEC) can obtain better recovery performance than conventional FEC mechanisms. As ADL FEC can also reduce acknowledgment frequency, it increases efficient and reduces power in the process. We validated the feasibility of ADL-FEC through our wireless sensor networks.
