摘要

为了使无线传感器网络(WSNs)的寿命最大化,提出了一种平衡速率区域覆盖算法(BRACA),以解决能量均匀性和平衡覆盖问题。该算法引入了均衡覆盖率的思想。并考虑了传感器对目标面积覆盖率的平衡和剩余能量作为滤波因素。通过调整传感器剩余能量与其平均覆盖率的比值,我们可以找到一个最大不相关和最小成本的传感器子集,以尽可能少的节点实现区域覆盖。实验结果表明,BRACA具有较好的计算效率。在保证wsn网络覆盖率不小于90%的前提下,e-coverage传感器子集消耗的能量较少且均衡,可以有效延长网络寿命。

Balanced rate area coverage algorithm
In order to maximize lifetime of Wireless Sensor Networks( WSNs),a balanced rate area coverage algorithm( BRACA) is presented,which aims at the problem of energy uniformity and balanced coverage. This algorithm introduces the idea of balanced coverage rate. And it considers the sensors' balance about target area coverage rate and the residual energy as filtering factors. By adjusting the ratio of sensor's residual energy to its average coverage rate,we can find a sensor subset with maximum uncorrelation and minimum cost,which achieves area coverage using nodes as few as possible. Experimental results show that BRACA has better computational efficiency. The e-coverage sensor subset can prolong network lifetime effectively due to consuming the less and balanced energy in the premise of ensuring the network coverage of no less than 90% in the WSNs.
