| 摘 要： | 提出一种在六边形覆盖约束条件下异构无线传感器网络的“突然死亡”能量消耗模型，该模型可以保证能量均衡消耗和网络寿命最大化。在该能耗模型基础上给出一种考虑节点能耗约束和数据完整性等因素的网络寿命模型，并求得网络寿命模型的最优解。仿真结果表明，构建在六边形覆盖条件下的异构监测传感器模型可以均衡网络能耗，且使网络寿命最大化。

| 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 nod... |
