Abstract
MANET is a special kind of wireless network. It is a collection of mobile nodes without having aid of established infrastructure. Mobile Adhoc network removes the dependence on a fixed network infrastructure by treating every available mobile node as an intermediate switch, thereby extending the range of mobile nodes well beyond that of their base transceivers. Other advantages of Manet include easy installation and upgrade, low cost and maintenance, more flexibility, and the ability to employ new and efficient routing protocols for wireless communication. In this paper we present four routing algorithm, classifications, discuss their advantages and disadvantages.
Highlights
Suppose it is required to and effectively connect two office floors using short range wireless communication devices
The major challenges that a routing protocol designed for Adhoc wireless networks faces are mobility of nodes, resource constraints, error-prone channel state, and hidden and exposed terminal problems
Routing protocols for Adhoc wireless networks can be classified into several types based on different criteria
Summary
Suppose it is required to and effectively connect two office floors using short range wireless communication devices. It is possible to connect these devices to the existing wired infrastructure using access points, but this option offers limited mobility, adds load on the wired networking and relies on existing protocols for wired communication. Another possibility is to build a network of dedicated and mutually connected base stations that enable cellular communication, but this is expensive with respect to time, installation, and maintenance. MANETs have been used primarily for military purposes, while commercial applications are just beginning to emerge. One of the potential practical usage scenarios of MANETs is in a conference room where a group of people
