Research on energy balancing of wireless sensor network fortransmission line monitoring

In the application of transmission line monitoring, the wireless sensor network has a serious unbalanced energy consumption problem. Features on the wireless sensor network like linear, regular and local compressed topology were utilized to resolve this problem. This paper proposed a cluster head rotation algorithm based on dense clusters and a routing algorithm based on address assignment. The algorithms had high scalability and could alleviate this problem by adding relay nodes. Simulation results demonstrate the effectiveness on energy consumption balancing and network lifetime prolonging.
