六边形覆盖条件下的HWSN最大寿命模型
Maximum Lifetime Model of Heterogeneous WSN in Hexagon Coverage Condition
摘要
Abstract
The heterogeneous surveillance sensor network energy consumption model which can balance the energy consumption and maximize the network lifetime is established. Based on the model and considering the factors of node energy restriction and data integrality, the network lifetime model of heterogeneous surveillance sensor network in hexagon coverage condition is presented. The optimal solution of the network lifetime model is obtained in hexagon coverage condition when the intra-cluster and inter-cluster key nodes almost run out of energy at the same time. Based on the network lifetime model, the minimum node density for satisfying a given lifetime constraint is gotten.关键词
