基于阿基米德螺线的双汇聚节点重定位策略
Archimedean Spiral Based Two-Sink Relocation Strategy in Wireless Sensor Networks
摘要
Abstract
In wireless sensor networks,unbalanced energy consumption among sensor nodes will lead to energy hole. Sink relocation can effectively balance energy consumption,and thus prolong the network lifetime. Compared with the single Sink,multiple Sinks have the advantages of reducing data transmission delay and improving data transmis-sion efficiency. In the paper, we propose an Archimedean spiral based multi-Sink Relocation strategy ( ATSR ) , ATSR takes advantage of Archimedean spiral having constant linear velocity and angular velocity,and then we adopt the way that Sinks move along two symmetric spirals of Archimedes to enhance the network lifetime. To improve ATSR further,we propose a better strategy(IATSR). Experimental results show our proposed ATSR and IATSR have better performance compared with other Sink relocation algorithms.关键词
