Abstract :
This letter proposes a novel forwarding scheme for reliable and energy-efficient data delivery in the cluster-based sensor networks. While multiple nodes in a cluster receive a packet, only one node among them is elected to send the acknowledgement back and then to broadcast it to the next cluster. With the binary exponential backoff algorithm for the election, the proposed scheme is more reliable and energy-efficient than existing forwarding schemes for the cluster-based sensor networks.
