基于能耗的协同感知消息传递方法

Method of Awareness Information Transmission Based on Energy Consumption

针对无线网络的断接性和移动终端的能耗问题,从保证协作者之间安全、可靠、高效的传递感知信息,减少感知信息的响应时间,达到节能目的的角度出发,给出了一个基于能耗的感知模型。使用消息队列收集感知信息,在网络断接的情况下在队列中缓冲消息,连接恢复时发送消息,从而保证了消息的流动性。同时,从节省能耗角度出发,采用上下文存储机制减小网络中传输的感知消息大小,减小响应时间,达到减少能耗的目的。最后,对协同感知方法的性能与几种典型方法进行了分析和对比,验证了本文方法的可行性和良好特性。

In accordance with some problems of wireless network, such as disconnection, bandwidth diversity, weak reliability, limits of power ability, a cooperative awareness model was presented based on energy consumption, which assures teams of workers to pass group awareness messages efficiently and reduce response time of messages, and also decrease energy consumption. In this model, awareness messages were collected using Message Queue, buffered under the condition of network disconnection and passed when connection restore normal status for keeping awareness information consistent across the network. And then, in accordance with the problem of energy consumption, energy was effectively conserved by applying context store mechanism to reduce size of awareness messages and response time. Finally, some experiments and their approach were conducted and compared with other message passing scheme, the evaluation results demonstrate the model is more efficient and feasible.
