摘要
现有的无线传感器网络模型较少考虑能量异构和负载均衡问题,并且对模型的评价方法有限。提出了基于新型局域世界的无线传感器网络模型,充分考虑能量异构、节点局域性以及加入负载调整因子,构建基于能量感知局域世界的无线传感器网络模型和基于负载调整局域世界的无线传感器网络模型,完善原有模型。利用MATLAB进行仿真,研究模型度分布等,提出用复杂网络的特征参数对模型进行评价,引入社会网络的中心性,更深入地评价网络节点重要性。理论分析和实验证明,该模型可以较好地描述无线传感器网络,可进一步优化网络和提高通信能力,同时复杂网络的研究思想对无线传感器研发具有指导作用。
The existing wireless sensor network model seldom considers heterogeneous and load balance.And evaluation method of the model is limited.This paper proposed a wireless sensor network model based on novel local world network and took heterogeneous as well as node localization and local adjustment factor into account.The new model concludes wireless sensor network model based on energy aware local world network and wireless sensor network model based on load regulation local world network,which perfects the original model.By using MATLAB to simulate,this paper studied the degree distribution of the model and proposed an evaluation method of the model by comparing the characteristic parameters of complex networks.It introduces centrality in social network field to evaluate the importance of network node more deeply.Both theoretical analysis and experiment show that new model can describe the wireless sensor network well and can further optimize the network as well as improving communication ability.The idea of complex network used in this paper has positive effect on the research of wireless networks.
