节点部署对网络的运行情况和寿命有很大的影响。论文通过无线多媒体传感器网络(WMSN)在井下救援系统的应用,研究了基于能量均衡的异构网络中通信节点部署问题。给出了在WMSN网络数据处理能耗不可忽略的情况下,网络不同层次的通信节点部署情况,并分析了多媒体传感器节点均匀部署和人工随机部署时,能耗分布和网络生存时间。仿真结果显示,利用文章提出的节点部署方法,能有效提高能量利用率和网络生存时间。
Node deployment operation has a great influence to the operation condition and lifetime of network. Theapplication of wireless multimedia sensor network (WMSN) in mine rescue system was introduced, and the deployment ofcommunication node in heterogeneous networks based on energy balance was studied. A scheme of communication nodedeployment in different levels was proposed, under the condition that data processing energy consumption couldn't beignored in WMSN network. The distribution of energy consumption and network lifetime was analyzed, when themultimedia sensor nodes uniformly deployed and artificial random deployed. The simulation results show that, theproposed node deployment method, can effectively improve the energy utilization rate and network lifetime.
