Research On Coverage Protocols For Sensor Networks

Wireless sensor networks have recently emerged as a premier research topic. They have great long-term economic potential, ability to transform our lives, and pose many new system-building challenges. Sensor networks also pose a number of new conceptual and optimization problems. Some, such as location, deployment, and tracking, are fundamental issues, in that many applications rely on them for needed information. Today, there are still many application cases can be designed, and many questions needed to be covered. It calls for the researchers to research deeply.Cover scheduling protocol is one of the key guideline for evaluating the sensor networks work performance. It provide a detailed statement about the network Quality and service. It can improve the allocation of the network source, and then perceive the environment, obtain information efficiently, and effective transfer. To ensuring the information completely, the node should decide the area is coved or not firstly. So, researching Cover scheduling protocol is very important.Cover scheduling protocol is research deeply in this paper. Regular probability model can not renew its probability as the network moving, like this will lead to performance drop, and has not expansibility. Neighbor nodes advising- probability model also has limitation, with increasing of the net work density, coverage of the network will decrease sharply. This paper analysis regular probability model and neighbor nodes advising- probability model, and then put forward a new protocol based on node energy and its neighbor information. Nodes adjust its sleeping probability according to its own energy and neighbor information. Let those nodes have high energy and more living neighbor nodes to sleep easily, to prolong the lifetime of the network.Furthermore, this paper analysis a distributed and location indifferent sensor net work cover protocol, and then improved it. The next lab indicate that the protocol has good ability. At last this paper introduces the lab platform and its designing process, this platform provide a lab environment.
