Energy efficient green routing protocol for Internet of Multimedia Things
Development of Low-power Low-rate wireless Networks (LLNs) based systems is prodigiously escalated, which helps realizing the notion of Internet of Things (IoT). Routing Protocol for Low-power and Lossy Networks (RPL) is the standard routing protocol for IPv6 LLNs. RPL has gotten tremendous appreciation due to its flexibility and adaptiveness to support dynamic application requirements in IoT. In this paper, we identify multiple issues in RPL route maintenance and recovery mechanism and investigate their drastic effects on the performance of RPL based on a simulation as well as an experimental study using Zolertia Z1 motes. In addition, the paper proposes an enhanced route maintenance and recovery mechanism to improve and rectify RPL operation. Performance analysis of the proposed scheme promise significantly lower reconnection time and high certainty in route recovery.
