DERACL: A Distributed Energy-efficient Routing Algorithm Based on Cross-layer Design

摘要

This paper proposes a distributed energy-efficient routing algorithm for mobile Ad Hoc networks (MANETs). We adopt the cross-layer design paradigm. The distance from the source node to the destination node is estimated based on the received signal strength indication (RSSI) of the packets and is used to adaptively adjust the backoff time of the MAC layer. A distance threshold and a packet count threshold are used to schedule the transmissions of packets in the Network layer. The algorithm is distributed and works without needing any global network information or control packet. Experimental results show that the routing algorithm is energy-efficient and drastically alleviates the Broadcast Storm Problem.
