Research On Access Control Of Power Wireless Network

Power wireless communication network is an important part of power integrated communications network, because of the extensive terminal information collection problem of the power communication network, a wireless communication channel access control policy and algorithm with the power information-gathering operations become one key technology of the intelligent network. In this thesis, a wireless communication channel access algorithm which fit to power business is researched to effectively meet communication requirements of the power communication network terminal information gathering business.In this thesis, the research is started from the analysis of the power information collection business and wireless communications network power applications environment, the systematic analysis of inductive power wireless communications data loss law and wireless private network communications capacity characteristics which is the basis of the study for the power operational characteristics channel access control algorithm. For the problem that wireless communication channel loss rate changs dynamic in power environments, an power wireless communications adaptive access control algorithm is proposed, which is combined with the power wireless communications data loss characteristics, and the dynamic selection cycle or competitive access policy is selected according to the channel loss rate in retransmission.The simulation experiment results show that the algorithm has higher communication reliability, timeliness, and wireless channel utilization. On the other hand, in connection with the problem of power wireless communication network’s communications capacity, a power wireless group access control algorithm is proposed, which is combined with power information gathering business communication capacity characteristics. In the algorithm, information collection terminals are divided into several groups, polling access control policy is selected in groups and regular report and random competitive access control policy is selected among groups. And the simulation experiment results show that this algorithm has a better network performance.
