We consider a Wireless Sensor Network where, due to limited radio link range, only some nodes have a direct contact with the base station and transmission is carried out in a multihop way. We propose a relation that represents cooperation between nodes and takes advantages of topological properties of the network. Based on the hop-distance from the BS any node k can determine a set N<(k) that consist of nodes to which k should send messages in order to retain a data-flow direction towards the BS.
