摘要：This study deals with the bang of cooperative routing for maximizing the network lifetime in sensornetwork applications. It is implicit that the nodes in the network are equipped with a single Omni directional antennaand they perform cooperative transmission to achieve transmit diversity. It is proposed as a joint cooperativetransmission and multi-channel interface energy aware routing algorithm to prolong the network lifetime. Thisapproach uses the maximum lifetime power allocation with multi-channel interface, instead of minimum powerallocation. Using the maximum lifetime power allocation, the cooperative nodes allocate their transmit poweraccording to the multi-channel condition and the residual energy in the nodes. The proposed scheme combines themaximum lifetime power allocation and the energy aware routing to maximize the network lifetime It is studied that theperformance of the cooperative routing in terms of network lifetime defined as the time until the first node dies and thetotal delivered packets before the first node dies. It is demonstrated that the proposed solution achieves one to three andhalf and one to two times longer network lifetime and more total delivered packets compared to non cooperativerouting, when it is used with MTE and FA algorithms, respectively. Furthermore, the maximum lifetime powerallocation achieves one to two times longer lifetime, compared to minimum power allocation in MTE and FA routineschemes. It provides distributed implementation of the proposed algorithm.
