论文摘要
无线传感器网络（WSN）的特征是由小型电池供电的设备网络进行远程操作，没有预先存在的基础架构。 WSN的独特结构允许新颖的方法降低数据和能量保存。本文通过提供了减少传感器数据减少的替代动作，从而减少了能源消耗，带宽的使用和消息传输时间，从而对现有的Q路由协议进行了修改。该算法得到了进一步修改，以包括一个能量因子，该能量因能量储量耗尽而增加转发成本。这鼓励网络节省能源，而当能源储备较低时，支持网络保存。我们的实验结果表明，在高网络流量的时期，这种方法可以同时减少带宽，节省能量并保持较低的消息过渡时间。
Wireless sensor networks (WSN) are characterized by a network of small, battery powered devices, operating remotely with no pre-existing infrastructure. The unique structure of WSN allow for novel approaches to data reduction and energy preservation. This paper presents a modification to the existing Q-routing protocol by providing an alternate action of performing sensor data reduction in place thereby reducing energy consumption, bandwidth usage, and message transmission time. The algorithm is further modified to include an energy factor which increases the cost of forwarding as energy reserves deplete. This encourages the network to conserve energy in favor of network preservation when energy reserves are low. Our experimental results show that this approach can, in periods of high network traffic, simultaneously reduce bandwidth, conserve energy, and maintain low message transition times.
