摘要
无线传感器网络(Wireless Sensor Network,WSN)中通信链路质量的好坏影响通信的效率与可靠性,因而研究影响WSN中包发送成功与否的原因具有现实意义。在一定范围内,节点间的距离和包的接收没有必然的关系。同时,由于应用程序设计的原因,只要节点在某一时刻没有收到包,就会在下一时刻出现丢包的情况。最后,来自无线局域网(Wireless Local AreaNetwork,WLAN)的干扰对WSN通信具有较大影响。
The communication quality in WSN produces an effect on efficiency and reliability. So, it makes sense to study the packet delivery performance. With a certain range, there is no necessarily relationship with distance and packet delivery. Owing to the design of application, there will be packet loss in next moment as soon as the node does not receive one packet at any moment. Finally, the interference from the WLAN does have great influence on WSN.
