A Survey on Issues and Challenges in RPL Based Routing for IoT
Main Article Content
Abstract
Internet of Things (IoT) is an emerging technology that is highly promising and can prove to be inevitable in every field in the near future. The function of the IoT devices is to collect data from the sensor and control the things over through the Internet. These smart devices can be controlled from any place, any time, without any equipment, and without the help of humans. The data collected from the sensor are routed between the users in the form of packets using wired or wireless medium. RPL (Routing Protocol for Low-Power and Lossy Networks) is the first standardized routing protocol for IoTenvironment that involves low power and lossy networks. However, it is observed that as the number of nodes and the density of nodes increase, RPL suffers in terms of quality of service offered due to a number of issues. In this paper, we identify the issues and challenges that affect the quality of service of RPL and also summarize the works that have effectively addressed some of these issues to improve the quality of service in the routing process.
