Abstract: In this paper,a cross-layer energy model for wireless sensor network is proposed,which takes the interaction with network layer,physical layer,channel as well as the impact of components in data link layer into account.How the important factors in the model effect energy consumption is identified by NS2 network simulations.And then a math model to calculate energy consumption is presented.And the parameters of the model are attained by fitting the NS2 simulation results,so that the formulas of energy consumption are obtained.

Key words: energy consumption formulas, cross-layer energy model, curving fitting, NS2 network simulation, wireless sensor network

摘要: 首先提出了一种基于无线传感器网络数据链路层的跨层能量模型。该能量模型考虑了网络层、物理层以及信道对能量损耗的影响。然后通过NS2仿真确定了模型中的重要因素对能耗的影响,并在此基础上推导了计算能耗的数学模型。最后通过对仿真结果的拟和得出模型中的参数,从而获得了能耗的计算公式。
