Research On Energy-Balanced Routing Protocols Of Wireless Sensor Netwok

Wireless sensor network is based on wireless communication technology, self-organizing and low-power dissipation network, general consists of a lot of the wireless sensor network nodes deployed in monitoring area and one or more base stations. With the related technology matures, wireless sensor networks have been in more and more use and shown enormous potential and application in many fields, so it will have a profound effect on people’s work and life in the future.Because of the sensor intensive and random distribution, small segments of the sensor will lead to premature death in the process of information transmission because energy consumption too fast, so the problem of network balance in wireless sensor network is a key research subject.According to the characteristics of wireless sensor network, the proposed design reasonable routing protocol, reduce the energy consumption effectively and obtain efficient and reliable transmission path, extend the lifetime of node and network, is very important to the development of wireless sensor network. There is a lot of research in wireless sensor network, this paper mainly researched the problem of network balance in wireless sensor network from the two aspects above.only from the above two aspects research network balance problems, the concrete content as follows:In chapter l,we start with the basic concept and theory of graph and network, describe wireless sensor networks and the architecture of wireless sensor networks,,introduce the wireless sensor network route.In chapter2, we introduce the research background and significance, as well as the research status of routing protocols in wireless sensor network at home and abroad firstly. Then it emphatically introduced about plane routing protocol and hierarchical routing protocol. Further more, we compare and analyze the classification of routing protocols advantages and disadvantages, ready for subsequent chapters.In chapter3, we put forward the routing protocol with penalty factor of wireless sensor network which considers two respects of energy balance and reliability. By adjusting the penalty parameter to make the network more balance, it can meet the requirements of practical applications, use the PSPRP algorithm to find the optimal path and illustrated by numerical experiments.In chapter4, we design the Energy-Balanced routing protocol based on probability of wireless.carrying out define a transmission strategy based on probability to augment the lifetime of network even further. In chapter5,we summarize the research, and look forward to the future in wireless sensor networks, show some open problems in network balance.
