PERFORMANCE EVALUATION OF RPL ROUTING PROTOCOL WITH DIFFERENT OBJECTIVE FUNCTIONS

Abstract

Nowadays, we stand before the digital revolution of the 21st century: smart objects are interconnected and connected to the Internet. It is predicted that the number of smart objects will reach billions of devices in the next 10 years. Routing Protocol for Low Power and Lossy Networks (RPL) proposed by the RoLL working group is a multi-hop routing protocol used for smart objects networks. In the RPL protocol, an objective function specifies parent selection and route construction based on routing metrics. In this paper, we evaluate the performance of the RPL routing protocol using two objective functions that are MRHOF and OF0. We use the Cooja tool to simulate and evaluate network performance. The evaluation results show that MRHOF performs better than OF0 in terms of average power consumption, successful data delivery ratio, and adaptive change in the network. In the poor quality of the transmission medium condition, MRHOF achieves significantly better performance than OF0.
