Directed Cooperation in Multihop Wireless Sensors Network This paper proposes a relational abstraction for Wireless Sensors Network where node can identify its neighbors around it. Because of limited radio link range only some of nodes have a direct contact with the base station and transmission is carried out in a multihop way so information is send from one node to another towards the BS. We propose a relation π that represents cooperation between nodes and takes advantages of topological properties of the network. Based on the hop-distance from the BS any nodekcan determine a setN<(k) that consists of nodes to which/kshould send messages in order to retain a data-flow direction towards the BS.
