A Study of Diverse Wireless Network

Abstract

Wireless network refers to any type of computer network that is not connected by cables of any kind. It is a method by which homes, telecommunications networks and enterprise installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. This article presents overviews of different wireless networks. It also discusses some characteristics difference of Mobile Ad Hoc Network, Wireless Sensor Networks and Wireless Mesh Network and compared each other with in the area of routing protocols, topology, traffic, inter-path interference, link capacity and channel diversity. I. Introduction Wireless telecommunications refers to the transfer of information between two or more computers that are not physically connected. Distances can be short, such as a few meters for television remote control, or as far as thousands or even millions of kilometers for deep-space radio communications. It includes various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Wireless cellular systems have been in use since 1980s. We have seen their evolutions to first, second and third generation's wireless systems. Wireless systems operate with the aid of a centralized supporting structure such as an access point. These access points assist the wireless users to keep connected with the wireless system, when they roam from one place to the other. Wireless telecommunications networks are generally implemented and administered using a transmission system called radio waves. This implementation takes place at the physical level (layer) of the OSI model network structure.
