“…As the packet is routed along a path towards the sink, the above steps of NMS algorithm except the neighbor list checking are executed at each hop so that reliable packet delivery can happen through a single path. This is in contrast to the previous schemes proposed in Morcos et al, 2005;Yang et al, 2005). In these schemes, a node broadcasts a packet without specifying a designated next-hop, and all neighboring nodes with smaller costs (the cost at a node is the minimum energy required to forward a packet from the node to the base station) or within a specific geographic region continue forwarding the packet to the base station.…”
