Overview of Proactive Routing Protocols in MANET

Abstract

Wireless mobile ad-hoc networks have gained a lot of importance in wireless communications. The communication has been established by nodes acting as routers and transferring packets from one to another in mobile ad hoc networks. In which, routing in these networks is highly complex due to moving nodes and hence many protocols have been developed. Such routing is the act of moving information from a source to a destination in an internetwork. During this process, at least one intermediate node within the internetwork is encountered. The routing concept in MANET involves two activities, determining optimal routing paths and transferring the packets through an internetwork. In this paper it is often deeply discussed about the different types proactive routing protocols used for mobile ad hoc networks and the reliability of proactive routing in the mobile ad hoc environment. It is a table driven routing method and each of the node maintains up to-date information on another node in the entire network.
