MPTC - A Minimum-Energy Path-Preserving Topology Control Algorithm for Wireless Sensor Networks
نویسندگان
چکیده
The topology control strategies of wireless sensor networks are very important to reduce the energy consumptions of sensor nodes and prolong the life-span of networks. In this paper, we put forward a minimum-energy path-preserving topology control (MPTC) algorithm. MPTC not only resolves the problem of exceeding energy consumption because of the unclosed region in SMECN[2], but also preserves at least one minimum-energy path between every pair of nodes in a communication network. At last, we demonstrate the performance improvements of our algorithm through simulation.
