Solved : Problem and Step-by-Step Installing NS-2.34 On Ubuntu 12.04 LTS

July 11, 2012

A few days ago, I installed my new PC in my lab with Ubuntu 12.04 LTS. I used to work with Ubuntu 10.04 LTS, but now I want to try Ubuntu 12.04. For my research purpose, I need to install Network Simulation NS-2 on it. As usual everything is not that easy while you’re going to work with Open Source or freeware…hehehe. That’s the challenges in Open Source. I like it.


Implementasi dan Analisis Kualitas Layanan VoIP Pada Jaringan Ad hoc Peer-to-Peer

April 15, 2012

Tri Angga Bagus Susanto1, Abdusy Syarif2, Abdi Wahab3

Teknologi VoIP (Voice over Internet Protocol) adalah sebuah teknologi komunikasi data yang sangat memungkinkan percakapan suara dengan memanfaatkan media jaringan komputer atau jaringan paket Internet Protocol (IP). Pada umumnya, implementasi VoIP menggunakan jaringan Local Area Network (LAN) atau Wireless Local Area Network (WLAN) atau juga Intranet / Internet. Singkatnya, dibutuhkan sebuah infrastruktur untuk dapat mengimplementasikan VoIP. Namun pada penelitian ini akan digunakan jaringan ad hoc peer-to-peer dan akan dilakukan pengukuran serta analisis terhadap kualitas layanan VoIP. Jaringan Ad hoc peer-to-peer adalah sebuah metode yang memungkinkan bagi perangkat keras nirkabel untuk berkomunikasi secara langsung dengan yang lainnya tanpa ketersediaan infrastruktur jaringan. Dalam skenario pengujian digunakan beberapa perangkat keras (seperti laptop, komputer dan telepon seluler), sistem operasi (Windows, Linux Ubuntu, dan Android) dan perangkat lunak softphone yang berbeda (seperti 3Cxphone, Ekiga, Qutecom, Sjphone, X-lite). Dari hasil penelitian dapat dilihat bahwa teknologi VoIP dapat diimplementasikan walaupun tanpa dukungan infrastruktur, yaitu dengan memanfaatkan jaringan Ad Hoc peer-to-peer. Dari hasil pengukuran dan analisa beberapa parameter yang diamati, didapatkan hasil untuk rata-rata delay adalah sebesar 20,54 millidetik, dan throughput sebesar 0,081 Mega Byte/detik, sedangkan banyaknya paket per-detik adalah 94,3842 paket.

Kata Kunci: voip, ad hoc, peer-to-peer

Insya’Allah paper ini akan dipresentasikan pada Seminat Nasional SNATI 2012 di UII-Yogyakarta pada tanggal 15-16 Juni 2012. 

Energy Consumption Analysis of AODV-UI Hybrid Routing Protocol under Various Mobility Models

December 26, 2011

This is our first draft joint research paper that we submitted to Networking 2012, The International Conference on Networking. This joint research is involved 2 universities, Universitas Indonesia and Universite de Haute Alsace-France. We hope that this paper could represent both universities in the conference.

Abstract – Mobile ad hoc networks (Manets) are characterized by mobile with portable and limited power sources. For more than one decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes attention and research focus on MANET widely. A lot of protocols proposed to improve and optimize AODV performance. Yet, many of those do not consider the needs of node accessing Internet via infrastructure network. In this paper, we proposed a optimize hybrid routing protocol based on AODV routing protocol, called AODV-UI. Our proposed protocol combines two mechanism such as gateway mode and reverse route mechanism with the aim to improve the performance of the hybrid protocol. We performed some evaluation of energy consumption calculation in our proposed hybrid protocol under various mobility models. We used random waypoint mobility models and reference point group mobility models with different speed and different number of source node to evaluate our protocol. The simulation result shows that our proposed protocol performance is lower in terms of energy consumption for random waypoint movement compare to the reference point group mobility model.

Keywords: Energy, gateway mode, mobility model, reverse route mechanism.

Autonomic Computing

September 25, 2011

About a week ago, my friend who take a double degree at UHA-France discussed about how to optimizing and securing AODV routing protocol. His Prof asked him to try ‘autonomic computing’. It’s sound like new to my ears. So, I’m trying to find out what is all about automatic computing?. Here is some of information about it. Let’s take a look.

Autonomic Computing refers to the self-managing characteristics of distributed computing resources, adapting to unpredictable changes whilst hiding intrinsic complexity to operators and users. Started by IBM in 2001, this initiative’s ultimate aim is to develop computer systems capable of self-management, to overcome the rapidly growing complexity of computing systems management, and to reduce the barrier that complexity poses to further growth. An autonomic system makes decisions on its own, using high-level policies; it will constantly check and optimize its status and automatically adapt itself to changing conditions. As widely reported in literature, an autonomic computing framework might be seen composed by Autonomic Components (AC) interacting with each other [1]. An AC can be modeled in terms of two main control loops (local and global) with sensors (for self-monitoring), effectors (for self-adjustment), knowledge and planner/adapter for exploiting policies based on self- and environment awareness.

Driven by such vision, a variety of architectural frameworks based on “self-regulating” autonomic components has been recently proposed. A very similar trend has recently characterized significant research work in the area of multi-agent systems. However, most of these approaches are typically conceived with centralized or cluster-based server architectures in mind and mostly address the need of reducing management costs rather than the need of enabling complex software systems or providing innovative services.

Autonomy-oriented computation is a paradigm proposed by Jiming Liu in 2001 that uses artificial systems imitating social animals‘ collective behaviours to solve hard computational problems. For example, ant colony optimization could be studied in this paradigm.[1]

Performance Analysis of AODV-UI Routing Protocol With Energy Consumption Improvement Under Mobility Models in Hybrid Ad hoc Network


In mobile ad hoc networks (MANETs), routing protocol plays the most important role. In the last decade, Ad hoc On-demand Distance Vector (AODV) routing protocol becomes the attention of focussed research on MANETs world wide. A lot of protocols had been proposed to improve and optimize AODV routing protocol to achieve the best in quest of reliable protocol. In this paper, we present some improvement suggestion to AODV routing protocol. Our proposed protocol, called AODV-UI, improved AODV in gateway interconnection, reverse route and in energy consumption. We also measure performance indicators for some metrics, such as energy, routing overhead, end-to-end delay, and packet delivery ratio. We performed our simulation scenarios with three mobility model with different maximum speed and sources in hybrid ad hoc network. The result shows that AODV-UI is more stable when it is used in random way point mobility model in any speed and number of sources.
