| Abstract: | To minimize and balance the energy consumption in the process of data transferring in wireless sensor network (WSN), we proposed a data gathering algorithm based on topology (DGAT) by dynamically constructingminimum spanning tree with communication energy consumption as the weight and a djusting node communication probability. DGAT changed the mode of communication and energy consumption of nodes in the network service process. Simulation results show that DGAT algorithm not only greatly improves the network lifetime, but also makes the network energy consumption more balanced. |
| Keywords: | wireless sensor network (WSN) network topology minimum spanning tree energy balance network lifetime |
