基于动态搜索区域的无线传感器网络小世界特性构建方案
A scheme of constructing small world network in WSNs based on dynamically searching zone
摘要
Abstract
In order to reduce the energy consumption of nodes in wireless sensor network (WSN) and thus extend the lifetime of wireless sensor network , this paper first studies how to prolong the lifetime of wireless sensor network through building small-world property, and emphatically analyzes the directed angulation towards the sink (DAS) scheme. To solve the problem that the energy of nodes near sink node use up quickly when the small-world property is constructed according to the DAS scheme, the diamond zone (DZ) scheme is proposed to construct small-world network for the WSNs. The DZ scheme can dynamically change the size of the searching area of shortcuts endpoint according to the distance between the sensor node and the sink node, therefore, the scheme can not only construct the small world networks for the WSNs, but also degrade the possibility of the nodes near the sink node to be selected as short-cut endpoints, decrease the energy consumption of these nodes and strengthen the invulnerability of WSNs. Additionally, through the comparison with the DAS scheme, the DZ scheme can extend the lifetime of WSNs under certain conditions.关键词
