In large sensor system, cluster-based network formation greatly contributes to the network lifetime, system scalability and energy efficiency. Network lifespan is the unique characteristic for measuring the utility of the sensor system. The important challenge in sensor network is the efficient use of energy for the sensor nodes. In this paper, the authors spotlight on balancing the power consumption and maximizing the network lifespan. In previous work, the problem is that number of duplicate data transmission occurs by multiple paths from the source to the sink.
