RAID the WSN: Packet-Based Reliable Cooperative Diversity
This paper introduces a light-weight packet delivery approach called Packet-based Cooperative Diversity to improve the reliability of Wireless Sensor Networks (WSNs). The authors' approach is based on the principle of cooperative diversity and failover concepts of Redundant Array of Independent Disks (RAID), by grouping, gathering, and rejecting redundant packets with the unique packet ID per message. It is suitable for nodes which require high reliability in message delivery but have enhanced energy capability. Their approach imitates two RAID levels to investigate their effect in reliability by redundancy.
