Analysis and Comparision of Position Based Routing Protocol in Mobile Adhoc Network
This Paper introduces the concept of ad hoc network and its applications. It also presents a brief review of conventional routing protocols and various routing approaches proposed for mobile ad hoc network. A brief description of various parameters used for performance evaluation of routing algorithms is also presented. An ad hoc wireless network is “a collection of two or more devices equipped with wireless communications and network capability” that creates a network “on the fly” without any network infrastructure. They offer quick and easy network deployment in situations where it is not possible otherwise. That’s why the idea of ad hoc networking is sometimes also called infrastructure less networking. Mobile Ad-hoc networks are self-organizing and self-configuring multi-hop wireless networks where, the structure of the network changes dynamically. This paper is intended to bring out the details of mainly two Position Based Routing Protocol named as LAR, DREAM. In position based routing the position (location) plays an important role in routing decisions. The position of a node can be made available by using GPS receivers or by evaluating relative positions using signal strength .Position based routing does not require knowledge of the entire network to find a route from source to destination Position based routing require that information about the physical position of the participating nodes be available and describing various parameters for LAR ,DREAM used by various authors and Proposed parameters for evaluating their performance.
