摘要

根据当前传感器节点的通信能力

提出了一种面向大规模无线传感器网络的数据传输方案(REDD).在方案中

节点间通过周期性的动态竞争产生簇首

形成分簇网络结构.簇内通信采用时分多路访问调度方式

成员节点在簇首分配的时隙内经由独立的簇内通信信道将监测数据发送至簇首.簇间通信采用载波侦听多路访问竞争方式

簇首间形成的连通覆盖网络通过多跳转发方式将聚合后的数据发送至网关.实验结果表明

较之已有的研究

REDD方案能够以更少的消耗达到更优的分簇性能

并且在保证可靠传输的同时有效降低传输时延.

Abstract

According to the communication capability of current sensor nodes

a novel scheme(REDD)is proposed for data delivery in large-scale wireless sensor networks. In REDD

the clustering network architecture is formed by periodically selecting cluster heads among sensor nodes through dynamic competition. The intra-cluster communication is based on TDMA scheduling

in which a member node transmits its sensory data through an independent intra-cluster channel to its cluster head in the time slot assigned by the cluster head. The inter-cluster communication is based on CSMA competition

in which a connected overlay network is constructed among all cluster heads to forward the aggregated data through multi-hops to the sink. Simulation results show that

compared with the existing work

the REDD can achieve a better clustering performance with lower costs

and effectively reduce the end-to-end delay for reliable data transmission.
