The direct communication between a sensor and the sink may force nodes to emit their messages with such a high power that their resources could be quickly depleted. Therefore, the collaboration of nodes to ensure that distant nodes communicate with the sink is a requirement. In this paper, messages are propagated by intermediate nodes so that a route with multiple links or hops to the sink is established. Wireless sensor networks can be used for many mission critical applications such as target tracking in battlefields and emergency response.
