随着处理技术、存储技术以及无线传输技术的不断发展,由体积小、重量轻、价格低的无线传感器节点所组成的传感器网络已经充分具备了感知客观事物及自然现象,随时随地为用户提供精确信息的能力。通过对于星状网、网状网和混合网等几种常用传感器网络拓扑结构的比较,以及针对这些拓扑结构所形成的网络寿命的仿真,说明了对于常用的基站距离远、节点密度大的传感器网络,分层式的拓扑结构能够大大的节省网络能量,延长网络寿命,改善网络性能。
With the continuous development of processing technology, storage technology and wireless transmission technology, the sensor network consisting of small, light weight and low price wireless sensor nodes has been fully equipped with the perception of objective things and natural phenomena to provide users with accurate Information ability. Through the comparison of several common sensor network topologies, such as star mesh, mesh network and hybrid network, and the simulation of the network life span formed by these topologies, it is shown that for the conventional base station with long distance and node density, Network, hierarchical topology can greatly save network energy, extend network life, improve network performance.
