无线传感器网络正受到广泛的研究关注,并在各种实际场景中得到应用。将无线传感器网络集成到工业制造过程中可以提供低成本的工业自动化系统。无线传感器网络的优点包括快速部署、自组织和免维护。然而,无线传感器节点是由电池供电的,部署后通常不可能更换或充电电池,这使得能量成为无线传感器网络的稀缺资源。此外,在工业应用中,环境信息被及时地收集和传递,这使得传统的节能方法(例如,休眠工作方式)效率较低。提出了一种基于分组到达率的动态地址编码方案,该方案通过减少MAC地址和网络地址的大小来减少协议开销,从而节省数据传输所需的能量。该方案的实现是完全分布式的,只需对现有应用程序进行少量修改。仿真结果表明,该方案在MAC层和网络层上都是有效的和鲁棒的。
Wireless sensor network is drawing intensive research attention and being applied in various practical scenarios. The integration of WSN in industrial manufacturing process provides low cost industrial automation systems. The benefits of WSN include rapid deployment, self-organization, and being maintenance free. However, wireless sensor nodes are battery powered; replacing or recharging battery is usually impossible after deployment, which makes energy a scarce resource for WSN. Furthermore, in industrial applications, environment information is gathered and delivered in a timely manner, which makes traditional energy saving methods such as listen-sleeping duty approach less efficient. In this work, a novel dynamic address encoding scheme based on packet arrival rate is proposed; the scheme can reduce the protocol overhead by reducing MAC and network address size and thus saves energy needed for data transmission. The implementation of the scheme is fully distributed and needs little modification of the existing applications. Simulation results show the proposed scheme is efficient and robust on both the MAC layer and the network layer.
