| 摘 要： | 传感器网络应用通常部署在如地下停车场、煤矿井下通道等条件复杂的环境中.这种复杂环境使短距离无线通信变得低效.早期传感器网络通信协议更多关注网络连通问题,较少考虑信道特性对协议的影响.随着对短距离无线链路特性认识的加深,人们尝试使用如链路估计、不相交多路径、缠绕多路径等机制提高网络抵达率和能量效率.通过模型分析了基于ARQ的多链路传输机制,给出该机制优于单链路的充分条件,同时分析了冲突对于网络效率的影响,并通过NS2验证模型分析的各项结论. |
| 关 键 词： | 无线传感器网络 多链路转发策略 ARQ机制 能量效率 抵达率 |

| Abstract: | Sensor network is frequently deployed in rather complex environment,such as underground parking lots,coal mine channels,etc.which are full of obstacles or corners.Such complicated situation brought a big challenge for protocol design,and made unreliable short distance wireless communication less efficient.Earlier protocol design for WSN paid more attention to the connectivity in on/off characteristics,neglecting link quality often in a middle value of 0 and 1 in the real world.As more knowledge on link feat... |
| Keywords: | wireless sensor network multi-link forwarding strategy ARQ mechanism energy efficiency delivery rate |
