Dengan menggunakan pendekatan algoritma genetik multi-obyektif evolusioner untuk mendapatkan solusi topologi jaringan sensor optimal dengan jumlah sensor seminimum mungkin, namun maksimum dalam hal jangkauan dan konektifitas.

Performance Analysis of Evolutionary Multi-Objective Based Approach for Deployment of Wireless Sensor Network with The Presence of Fixed Obstacles

Here is the abstract from our paper that already accepted and will be presented on Globecom 2014 that will be held in Austin, Texas, USA from 8 – 12 December 2014.

Abstract — In this paper, a study about wireless sensor network (WSN) deployment strategy is demonstrated and made workable for the use of multi-objective approach. The development of sensor nodes by considering multiple objectives and existence of fixed obstacles is an important optimization problem. There are two objectives in this study, connectivity and coverage as two fundamental issues in wireless sensor networks deployment. In this work a multi-objective evolutionary algorithms based on elitist non-dominated sorting genetic algorithm (NSGA-II) is proposed to address this problem. Two proposed functions, ranking function and fitness function, are used to determine the best optimal solution from Pareto optimal fronts. Further we presented simulation and analysis to verify and validate the deployment of wireless sensor network in area with the presence of permanent obstacles.

Keywords — Multi-objective optimization, Wireless Sensor Network, Deployment, Genetic Algorithm, Obstacle.

Evolutionary Multi-Objective Based Approach for Wireless Sensor Network Deployment

Here is the abstract from our paper that already accepted and will be presented on ICC 2014 (International Conference on Communication) that will be held in the beautiful city of Sydney, Australia from 10-14 June 2014.

Abstract: A multi-objective evolutionary algorithm is designed to address some problems in many fields. This paper is a study about deployment strategy for achieving coverage and connectivity as two fundamental issues in wireless sensor networks. To achieve the best deployment, our approach is based on elitist non-dominated sorting genetic algorithm (NSGA-II). There are two objectives in this study, connectivity and coverage. We defined a fitness function to achieved the best deployment of nodes. Further we performed simulation to verify and validate the deployment of wireless sensor network as an output from our proposed mechanism. We measured some performance parameters to investigate and analyze our proposed sensor-deployment. Our simulation results show that our proposed algorithm can maintain coverage and connectivity in given sensing area with a relatively small number of sensor nodes in a given area.

 

Comparison and Performance Analysis of AntNet and Distance Vector Routing Protocol in Telecommunication Networks Case Study : XYZ Company

This is my abstract from our paper that already accepted and will be presented on ICOICT (International Conference of Information and Communication Technology) that will be held on 20-22 March 2013, at The Trans Luxury Hotel in Bandung, Indonesia.

Abstract—In this paper, we learn and adapt ant colony algorithm to know about the quality of services of routing protocol in broadband backbone infrastructure of XYZ Company. The objective of this research is XYZ Company need a basic research reference to realize broadband services such as Internet Protocol Television (IPTV) and digital television with the existing network infrastructure. In other words, company should not buy and build a new infrastructure to apply a new service. In that way the budget to buy new expensive devices could be allocated to another aspect. We perform our work by using simulation NS-2. In our method, we assume that all nodes are a router. We show through our deep experiments based on real network topology and also we compare AntNet routing protocol with distance vector routing protocol to learn their behavior and performance. The simulation result shows that AntNet routing protocol is better than distance vector in term of packet delivery ratio for larger packet size. However, in term of routing overhead and delay, AntNet produces higher header packet than distance vector routing protocol.

Energy Consumption Analysis of Modified AODV Routing Protocol under Random Waypoint and Reference Point Group Mobility Models

Abstract — A Mobile Ad hoc Networks (MANET) is a non-infrastructure network that consists of a collection of nodes that can communicate each other independently. MANET is characterized by mobile with portable and limited power sources. A lot of protocols proposed to improve and optimize AODV performance. Our previous work, we have proposed a modified AODV routing protocol called RAODV+. RAODV+ combines two mechanism such as gateway mode and reverse route mechanism with the aim to improve the performance of the hybrid protocol. In this paper, we will discuss and analyze our modified AODV routing protocol in term of energy consumption analysis in mobility models, random waypoint and reference point group mobility. In this work, we use network simulator NS-2 to perform some scenarios of simulation. We used mobility models random waypoint and reference point group with various speed and number of source node to evaluate the energy consumed by each node. The simulation result shows that our modified protocol has lower energy consumption for random waypoint movement compare to the reference point group mobility model.

Tri Angga Bagus Susanto¹, Abdusy Syarif², Abdi Wahab³

ABSTRAKS
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.

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

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.

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

Abstract

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.
