The routing over Low Power and Lossy network working group (ROLL) has specified RPL as an IPv6 routing protocol for Low Power and Lossy networks. RPL builds a Destination Oriented Directed Acyclic Graph (DODAG) based on a set of metrics and constraints trough a specific Objective Functions (OFs). This OF can specify the selection of the parent and the construction of the route. In this paper, the performances of RPL are analyzed based on two main objective functions: Minimum Rank with Hysteresis Objective Function (MRHOF) that uses number of expected transmission (ETX) as a condition to select the routes and the Objective Function Zero (OF0) based on the Minimum Hop Count to determine the best parent. The analysis of RPL performances with the two comparative Objective Function is made with different metrics such as ETX, Hop Count, lost packet, energy, and control traffic overhead. This comparison makes it possible to distinguish which objective function is the most optimal to guarantee good functioning of RPL especially in mobile environment and which one respond better to the requirements of its application.
