全覆盖需求的水下传感器网络覆盖保持算法
Full-Coverage Required Coverage-Preserving Algorithm for Underwater Sensor Networks
摘要
Abstract
In Underwater Sensor Networks, it usually requires meeting the demand for full coverage over the targeted region, which directly reflects the network quality of service ( Qos). In order to extend network lifetime of full coverage, we propose a full-coverage required coverage-preserving algorithm for Underwater Sensor Networks (FCCP). At first,the algorithm elects the root node by constructing a cover set,each element of the cover set could cover the sensing region of the node partially or completely. Then,make the redundant nodes of the network sleep, each node chooses the node with the highest coverage redundancy(CR)in the parent nodes as the next hop node, and form a tree routing. Finally, each node sends the sensed data to the Sink node using multi-hop routing. Compared to the energy-aware coverage-preserving hierarchical routing protocol ( ECHR) for the purpose of full coverage, FCCP effectively reduces network energy consumption and extends the network lifetime of full coverage.关键词
