摘要/Abstract

摘要： 无线传感器网络节点能量有限，网络生存周期受限，这使得功率控制成为研究的热点.在带状拓扑情况下，离汇聚节点近的节点数据转发量大，能量消耗也快，成为网络的瓶颈.该文主要研究一种改进的功率控制算法，在增加瓶颈节点的生存时间的同时，保证上行数据传输的连通性和扩展下行数据传输功能，优化整个网络的性能.

Abstract: Due to energy limitation, wireless sensor networks are limited in life span. Therefore power consumption control has been a hot topic. In belt-shaped topology, relay nodes close to the sink must forward more data than those far from the sink. They inevitably consume more energy, therefore are exhausted quickly and become a bottleneck of the network. This paper aims to improve a radio range adjustment algorithm to increase lifespan of the bottlenecked nodes by ensuring network connectivity for uplink traffic and acceptance for downlink traffic.

Key words: power control, wireless link unidirectivity, wireless sensor network
