Mobility-Aware Energy-Efficient Link Recovery Routing Protocol for Low Power and Lossy Networks

Abstract

IPv6 Routing Protocol for Low Power and Lossy Networks (RPL) is developed and standardized by the Internet Engineering Task Force (IETF) for energy-constrained networks in IoT. In many IoT applications like health monitoring, tracking vehicles, tracking livestock, military surveillance, or monitoring of any area requires mobility of devices. When the nodes are mobile, maintaining the reliable link is a critical issue in IoT as mobile devices may move away from radio range and it would lead to disconnection from its parent node. This link failure affects network performance. Energy-efficiency is also another challenge as link failure results in energy depletion. So, we need a routing protocol that will support the mobility of devices and which is energy efficient with the link recovery technique. In this paper, we have proposed a routing protocol for Low Power and Lossy Networks that will provide mobile nodes with a link recovery technique, hence named as, Mobility-Aware Energy-Efficient Link Recovery Routing Protocol for Low Power and Lossy Networks. The network building process used in this paper is a Destination Oriented Directed Acyclic Graph (DODAG). DODAG has all the control messages which are used for routing protocol for organizing the routers. The Trickle Algorithm is used by the proposed RPL to maintain the route. The proposed protocol is simulated and compared with a similar routing protocol. The Simulated results show that the proposed protocol provides less energy consumption and a more packet delivery ratio as compared to the existing protocol.
