应急通信中WSN系统模型及性能评价指标体系研究

Investigation of System Model and Performance Evaluation Index System of Wireless Sensor Network in Emergency Communication

应急通信环境复杂多变,对无线传感网的服务能力提出了更高要求。本文给出了一种适用于应急通信的WSN的系统模型,并就网络拓扑、部署方式、感知模型、能耗模型以及覆盖和连通性进行了说明。然后,在介绍常规网络服务评价指标的基础上,归纳总结WSN的性能评价指标体系。最后,对全文进行了小结。

Emergency communication environment is complicated and volatile, posing higher requirements for service capability of Wireless sensor network （WSN）. In this paper, a system mode suitable for WSN in emergency communication is proposed. In this system model, network topology, deployment manner, sensing model, energy consumption model, coverage and connectivity of WSN are expounded. Then, on the basis of introducing QoS evaluation indexes of general networks, performance evaluation index system of WSN is concluded. At last, summarization of the paper is given.
