Traffic analysis between two neighbor ad hoc network under channel interference

In the modern era, the use of ad hoc networks is a common in all government offices, universities and industrial unit and so their use grows every day. Deploying an efficient and reliable network is big challenges among network designer due to various problems such as proper AP location, good signal strength and channel interference. Channel interference is also one of them which must be taken in to account when deploying WLAN indoor environments because channel interference affects the network the network performance. In this work, our basic purpose is to only study the performance between two neighbor ad hoc networks under channel interference. Here we create two WLAN IBSSs (using nodes and server) for analyze performance. Initially they are positioned far from each other but nodes of one network moves toward another network during simulation and after some time both BSSs overlaps to each other. When both BSSs overlaps to each other interference is more and reduce network performance and increase upload time.

I. INTRODUCTION

In recent times, the use of Wireless local area networks (WLAN) replaces wire network because wire technology is expensive and sometime it is prohibitive to lay cables. Wireless networks have advantages for notebooks and other small computer equipment for getting access to the internet due to easy installation and maintenance. This wireless technology has a various other characteristics that enable the user to access network without having wired connections. The wireless system keeps the user free from being restricted to the use network in limited location such as their rooms, corridor, and computer laboratories. Wireless network also eliminates any time restrictions associated with traditional wired network. In short, a WLAN will enable the user to access information and communicate any time and anywhere within coverage area. Wireless network at the educational institutions is being used to connect staff and students to outside corporate network. An analysis, found that the use of WLAN at educational institutions is a good for preparing a suitable study environment for the students, and enhance the work capacity of the current students and staffs. Most of the universities are switching over from wire to wireless technology, there are some of them use both wire and wireless.
