摘要
针对现有传感器网络在无线视频应用中,簇首选取较少考虑剩余节点能量、不利于提升网络使用寿命和降低组网成本的缺点,提出一种基于虚拟势场的无线视频传感器网均衡协议。首先,对无线视频传感器网络结构及模型进行研究,给出其网络结构、能耗模型及感知模型;在上述模型基础上,从能耗均衡角度进行簇首选取,有效提高网络使用寿命,并利用改进的虚拟势场对传感器节点的感知方向进行调整,提高传感器节点覆盖范围,降低组网成本。最后,通过算法的仿真实验对比表明,所提协议可有效提升网络使用寿命和视频监测区的信号覆盖率。
At present, current sensing system for wireless network in the practical field of wireless video, especially for cluster head selection and analysis, has not been fully considered to the resources energy of the remaining nodes in this area, therefore it lacks the support for wireless networks for a limited period of extension, and reduces the network cost etc. This paper proposed a balanced agreement of the video communication sensor system network based on a simulation of potential field. First, it took scientific analysis and discussion for video communication sensing system corresponding to the network system as well as the specific appearance, built a corresponding Wireless network system model, resource consumption system architecture also included induction system architecture. Second, based on above model, focusing on the resources consumption balance, it selected and filtered the cluster head to extend the validity period of the wireless system architecture effectively. Based on simulation experiment, it took effective treatment to different range of sense for the potential sensing system to improve and expand all the range of sensing system, thus greatly reduced the network cost required. The simulation results based on scientific comparison are not difficult to find, the new protocol can enhanced effective operation cycle of wireless system, and improve the effective coverage ratio range in the video exploration area.
