We analytically characterize the energy consumption per successfully transmitted packet in end-to-end packet transmissions in a wireless sensor network where nodes are identically and independently distributed in a square area following a homogeneous Poisson process. It is assumed that a greedy forwarding protocol is used for routing. We obtain analytical results on the average number of hops between...
Data forwarding schemes that use a single ACK-based retransmission mechanism are widely used to increase the packet delivery ratio in wireless sensor networks. However, these schemes may waste a considerable amount of energy for data transmissions, especially when the link quality is low for ACK transmissions. In this paper, we propose a novel multi-ACK-based data forwarding scheme to minimize the...
