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

December 16, 2020


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.

Since October 2017, I have been involving as a member of International Joint Research (IJR) project between 3 institutions (2 France, 1 Indonesian). Currently I’m an associate professor at UMB (maybe until [month] 20[xx] 🙂 ) and a PostDoc fellow at CESI Starsbourg, France, as a part of joint research between UMB-UHA-CESI. We have started our project on December 2017. (more…)

Sejak tanggal 1 September 2010, saya mendapat SK pemberhentian sebagai ‘Ketua Jongos’. Dan memulai suatu aktifitas baru, jadi ‘pelajar’ lagi. Setelah berjalan 2 bulan, ternyata makin terasa sekali beratnya menjalani tahapan aktifitas ini. Terutama ketika harus menjalankan dan menyeimbangkan antara aktifitas sekolah, pekerjaan, dan keluarga. Kebutuhan keluarga atau pribadi adalah sesuatu yg tidak dapat ditunda. Berbeda dengan sekolah dan pekerjaan yang masih mungkin dapat ditunda.

Tanggal 3 November 2010, salah satu fasilitas yang telah diberikan oleh Penguasa Kampus adalah telepon Flexi Pasca bayar saya telah di non aktifkan. Walaupun saya mengerti, ini adalah kekuasaan sang Penguasa Kampus untuk mencabut ‘nyawa’ dari telepon saya. Namun alangkah manusiawinya jika ada konfirmasi terlebih dahulu. Misal dengan memberikan surat pemberitahuan baik via telepon atau email. Siapapun pasti akan merasa enak jika diperlakukan manusiawi bukan?
