Performance Analysis of RPL Protocols in LLN Network Using Friedman’s Test

December 16, 2020

Abstract

This paper provides a comparison study of the quality services of RPL protocols in low-power and lossy networks (LLN). We evaluate and compare our proposed protocol which is an extension of RPL based on Operator Calculus (OC), called RPL-OC, with the standard and other RPL variants. OC based approach is applied to extract the feasible end-to-end paths while assigning a rank to each one. The goal is to provide a tuple that containing the most efficient paths in end-to-end manner by considering more network metrics instead of one. Further, to address some significant issues of the performance analysis, a statistical test has been performed in order to determine whether the proposed protocol outperforms others or not by using Friedman test. The results show that there is a strong indication that four different protocols were analyzed and compared. It reveals that the proposed scheme outperforms others, especially in terms of end-to-end delay and energy consumption which allow ensuring quality of services requirements for Internet of Things (IoT) or smart city applications.

This paper has been already accepted on the Symposium on Solutions for Smart Cities Challenges 2020 (SSCC 2020) in conjunction with The Seventh International Conference on Internet of Things: Systems, Management and Security (IoTSMS 2020), Paris, France, December 14-16, 2020. Accepted papers will appear in the IoTSMS Proceeding and to be submitted to IEEE Xplore for inclusion. And in addition, this paper is one of the Workshops Best Paper Nominees. However, due to pandemic Covid-19, the conference is transformed into an online virtual conference.

Visit to UHA-Colmar, France

November 9, 2011

These are some pictures of my journey when we had visiting  our research partner at Universite de Haute-Alsace (UHA) at Colmar, France on 8-9 Nov 2011.

Just sharing a little story about Colmar, France. Colmar is a small town in highland of east France. It’s about 500 KM from Paris, or 3.5 hours by TGV. When I was there, the temperature was around 15 Celcius at day and 8 Celcius at night. Because this November is winter time in Europe.

The meeting was attended by Prof Bagio Budiradjo (UI), Prof Pascal Lorenz (UHA), Dr. Abdelhafid Abouaissa (UHA), Harris Simaremare (Co-tutelle student) and me. We also visited labs & facilities campus at UHA.

 

 

And finaly, we have dinner together.
