Adaptive error control using ARQ and BCH codes in sensor networks using coverage area information

This paper proposes adaptive error control strategies for wireless sensor networks using informational value of messages. The informational value is based on sensors coverage area. Important packets are protected by more powerful error control schemes than less important packets. BCH codes and retra...

Description
Summary:This paper proposes adaptive error control strategies for wireless sensor networks using informational value of messages. The informational value is based on sensors coverage area. Important packets are protected by more powerful error control schemes than less important packets. BCH codes and retransmission schemes were analyzed using OQPSK modulation in Rayleigh fading channels. The results obtained show that the adaptive schemes improve the reliability of packets with high informational value without a significant increase in the energy consumption.
