WIRELESS AD HOC ROUTING PROTOCOLS Raghav Thirani , Monica Chandil ABSTRACT: An ad hoc network is a collection of nodes which are dynamically located in such a manner that their inter connections might change on continual basis. A routing protocol is required, to facilitate communication inside the network by discovering routes between the nodes. This research paper classifies various protocols and provides an overview about eight different protocols under varied categories. 1. INTRODUCTON: Since their emergence, wireless networks have become increasingly popular. There are currently two kinds of wireless networks in use, namely WLAN’s and Ad Hoc. WLAN’s are called infrastructure networks as they have fixed and wired gateways, whereas Ad hoc are called infrastructure less networks as they don’t have any fixed routers, all nodes in this are capable of movement and can be connected…show more content…
It starts by throwing light on Table Driven or Proactive routing protocols, then moving forward to On -demand or Reactive routing protocols. It further discusses about Hybrid routing protocols which are a mixture of the previous two. We end the discussion on these routing protocols by introducing the Hierarchical routing protocols. 2. TABLE DRIVEN PROTOCOLS Table driven routing protocols are also called as proactive routing protocols. They try to maintain the consistent, up to date routing information from each node to every other node in the network[1]. Nodes respond to network topology changes by propagating route updates throughout the network.[1] in this paper we discuss three proactive routng protocols namely: Optimised Link State Routing protocol(OLSR) , Destination Sequenced Distance Vector Routing(DSDV) and Wireless routing protocol (WRP). 2.1 DSDV: In this routing protocol, every node maintains a routing table which has got entries of all the possible destination nodes and the number of hops to each of
