IP based Wireless Sensor Networks (IP-WSNs) are being used in healthcare, home automation, industrial control and agricultural monitoring. In most of these applications global addressing of individual IP-WSN nodes and layer-three routing for mobility enabled IP-WSN with special attention to reliability, energy efficiency and end to end delay minimization are a few of the major issues to be addressed. Most of the routing protocols in WSN are based on layer-two approaches. For reliability and end to end communication enhancement the necessity of layer-three routing for IP-WSNs is generating significant attention among the research community, but due to the hurdle of maintaining routing state and other communication overhead, it was not possible to introduce a layer-three routing protocol for IP-WSNs. To address this issue we propose in this paper a global addressing scheme and layer-three based hierarchical routing protocol. The proposed addressing and routing approach focuses on all the above mentioned issues. Simulation results show that the proposed addressing and routing approach significantly enhances the reliability, energy efficiency and end to end delay minimization. We also present architecture, message formats and different routing scenarios in this paper.
基于 IP 的无线传感器网络（IP-WSN）正在医疗保健、家庭自动化、工业控制和农业监测等领域得到应用。在这些应用中，大多数都需要解决以下几个主要问题：为了实现 IP-WSN 节点的全局寻址和移动性的三层路由，以及对可靠性、能效和端到端延迟最小化的特别关注。WSN 中的大多数路由协议都是基于二层方法的。为了提高可靠性和端到端通信，研究社区对 IP-WSN 中使用三层路由的必要性产生了浓厚的兴趣，但由于维护路由状态和其他通信开销的障碍，无法为 IP-WSN 引入三层路由协议。针对这一问题，本文提出了一种全局寻址方案和基于三层的分层路由协议。所提出的寻址和路由方法着重解决了上述所有问题。仿真结果表明，所提出的寻址和路由方法显著提高了可靠性、能效和端到端延迟最小化。本文还介绍了体系结构、消息格式和不同的路由场景。
