| 摘 要： | 由于无线传感器网络中节点的数量多和节点能量不足等原因,往往所有网络节点传输整个新程序要耗费相当长的时间,造成网络再进入工作的周期长.另一方面,有的节点由于能量不足,新程序未接收完就不再工作,这也浪费了大量的时间、耗费发送节点的能量和增加了网络流量.无线传感器网络即时响应网络再编程机制采用能量不足节点不给予新程序机制及采用固定跳、拉线方式将新程序传输到节点,线上的节点将新程序复制到其中的一个邻居节点后,立即开始执行采集、处理数据等功能的机制.从理论上分析了该机制可以节能能量和缩短第一响应时间.

| Abstract: | Because of the limitation of energy and the huge number of nodes in a WSN, it takes a long time for all nodes to transmit a new program then the working period of the network becomes longer. On the other hand some nodes cease working before receiving all new program because of shortage of energy, and this causes quite a lot waste of time and energy and makes the network traffic heavier. Prompt Response network reprogramming mechanism for wireless sensor network will avoid sending new program to those nodes which have insufficient energy. It will send new program to those nodes which stand in line within regular hops, then copy new program to one of their neighbors , and after that, acquisition and data processing start, The advantages of this mechanism has been theo- retically proved. |
