Wireless Video Sensor Network Equilibrium Protocol Based on Simulated Potential Field

In the present, current sensing system for wireless network for wireless video in the field of practical, especially for cluster head selection and analysis, has not been fully considered to the remaining nodes of the resources of energy in this area, Therefore lacks the support for wireless networks for a limited period of extension, and reduce the network cost etc., so the following is analysis balanced agreement of a simulation of potential field of the video communication sensor system network architecture. First, especially for video communication sensing system corresponding to the network system as well as the specific appearance take scientific analysis and discussion, to build a corresponding wireless network system model, resource consumption system architecture also includes induction system architecture. Second, based on above model, by the consumption of resources of balance to focus, cluster head selection and filtration, in large measure up to extend the wireless system architecture of the validity period of time, also based on simulation experiment, the potential for sensing system for different range of sense should trend to take effective treatment and to improve and expand all the range sensing system of radiating surface, thus greatly reduce network cost required and cost; Which must be mentioned is that between the calculation scheme of the simulation results based on scientific comparison is not difficult to find, the new protocol can be enhanced wireless system effective operation cycle is very good, and the effective range of the video exploration emission radiation frequency ratio.
