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.

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.

TCL Script for My NS-2 Project

This is my simple tcl script for our project research by using NS-2.34. In this project, we are going to combine 2 protocols, AODV+ and R-AODV,  our proposed protocol called AODV-UI.

Here is the tcl script.
