摘　　要：无线传感网络WSNs(Wireless Sensor Networks)是由资源受限的节点构成。而能量是节点最稀缺资源,据此需要保存能量,才能优化网络寿命。为此,先分析了通过平衡能耗优化网络寿命问题,然后提出基于阿基米德螺旋的WSNs节点部署的能耗均衡算法AS-DBEC(Archimedes’Spiral-Based Deployment balancing energy consumption algorithm)。AS-DBEC算法提出基于阿基米德螺旋的部署函数,将阿基米德螺旋转换成离散形式,再将节点部署于离散位置。最后,评估了AS-DBEC算法在能耗均衡和网络寿命方面的性能。Wireless Sensor Networks(WSNs)are comprised of resource-constrained nodes.One of the scarce resources of nodes is energy,which needs to be preserved in order to optimize network lifetime.Therefore,we have analyzed the problem of network lifetime optimization by balancing energy consumption,and have proposed Archimedes’Spiral-Based Deployment balancing energy consumption algorithm(AS-DBEC)in this paper.A deployment function based on Archimedes’spiral is proposed,and Archimedes’spiral be transformed into a discrete form so that may be deployed at those discrete locations.The performance of the optimal clustering strategy is evaluated in terms of energy balance and network lifetime.
