With Hibernation Define K (K = 1) Parallel Poll Service For Wireless Sensor Network Control Protocol Analysis

With development of and maturity of the level of wireless communication, the scale of integrated circuits and wireless sensor technology, the miniature smart sensors with a certain perception, certain information processing and certain transfer capability widely are applied to every corner of life of the actual production. The wireless sensor network is composed by many tiny smart sensors. So each node with weak computing capacity is composed of an object to the type of network topology and connection entity by WSN, that the plurality of single nodes able to perceive the information for certain consolidated. This technology has aroused great concern.Due to the limited resources and the random needs led to the existence of queues, and the polling as a special queuing system is uncompetitive. The site uncompetitive channel to avoid the collision. Able to meet with higher requirements for real-time services, such as voice, video, and other service.Excellent network performance of the PCF, the PCF applications in local area networks and ad hoc networks, networking sites can continue to supply power, it is more performance considerations in terms of QoS, and for energy consumption, that is, how to increase energy efficiency is not very concerned about. In this thesis, research is under the careful guidance of the mentor polling control mechanism based on for the traditional PCF and DPWPAP agreement to join the mechanism of dormancy, propose a more suitable WSN MAC layer protocol, the agreement has a strong focus on the previous polling protocol consider energy-saving, and the idea of parallel processing site for conversion and site services. Multidimensional probability generating function and the Markov chain model agreement to establish a system to draw the theoretical analysis and experimental model in MATLAB simulation, first verify the correctness of theoretical analysis, comparative analysis of the traditional PCF and with sleep parallel the limited (k=1) polling system average queue length and energy consuming, simulation results show that the agreement significantly reduces the energy loss of nodes.
