Network-Coding-Based Cooperative ARQ Medium Access Control Protocol for Wireless Sensor Networks

The authors introduce a novel Medium Access Control (MAC) protocol for Automatic Repeat reQuest-based (ARQ-based) cooperative wireless sensor networks. Using network coding techniques, they achieve a better network performance in terms of energy efficiency without compromising the offered Quality of Service (QoS). The proposed solution is compared to other cooperative schemes, while analytical and simulation results are provided to evaluate the protocol. Wireless Sensor Networks (WSN) has experienced an impressive growth during the last years. Their inherent restrictions (battery, processing power, etc.) along with their special characteristics (e.g., large network size) constitute great challenges for further research.
