基于阿基米德螺旋的WSNs节点部署的能耗均衡算法

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.

Archimedes' Spiral-Based Deployment Balancing Energy Consumption Algorithm in Wireless Sensor Networks

Wireless Sensor Networks(WSNs)are comprised of resource-constrained nodes. One of the scarce re-sources of nodes is energy,which needs to be preserved in order to optimize network lifetime.Therefore,we have an-alyzed 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 deploy-ment 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.
