Implementation of network layer protocols in wireless networks for efficient routing

Abstract

A simple framework for designing protocols for wireless networks includes localized routing and broadcasting. The simple framework is based on the ratio of the cost of making certain decisions such as reduction in distance count. Routing protocol is one of the major networks found in this application of wireless networks. The commonly used routing techniques in the network layers are described as follows. In [1]Distributed routing approach each node checks whether the cost of routing via a given neighbor is smaller than that of currently used nodes. In the `adhoc' networks, it has bandwidth limitation of the wireless channel. In dynamic ad hoc networks, a localized approach based on `on-demand route discovery' by flooding destination is used. But it is inefficient to use flooding as routing scheme in wireless networks since it has power and bandwidth limitation. Localized protocols describes the amount of information required (i.e.) it gives the average number of messages transmitted per node in a protocol. In a strictly localized protocol it is either local or global in nature. Thus the goal of the project describes the concept as a general framework of some existing protocols. The Proposed framework of the localized routing scheme is based on the cost measure, which depends on the assumptions for the minimal routing path to be selected and the progress measure depends on the advances towards the destination. Network simulator is used to implement this scenario.
