Abstract
A MANET can be treated as a network in which the nodes have the capability of self-configuring among themselves. These nodes are connected by wireless links to form an distributed topology without the help of any pre-existing infrastructure. Each node in a MANET can itself act as a router on its own. To perform effective routing operation in MANETS , several routing protocols were proposed, addressing several issues in MANETS. In this paper ,we tried to study the operation of DSDV protocol ,which is a proactive protocol and analyse the results obtained by simualting the DSDV protocol using NS-2 Simulator.
Highlights
With the recent changes and advancements in computer and communications technologies, under wireless communications, there is a widespread use of mobile computing applications using the TCP/IP protocol stack
Destination-Sequenced Distance-Vector Routing (DSDV) is one of the earlier ad hoc routing protocols developed. n DSDV, packets are routed between nodes of an ad hoc network using routing tables stored at each node
We have implemented the routing protocol DSDV for MANET’s and compared the results obtained with our proposed protocol with different no. of malicious nodes to identify the performance of the network under different scenarios
Summary
With the recent changes and advancements in computer and communications technologies, under wireless communications, there is a widespread use of mobile computing applications using the TCP/IP protocol stack. MANETS were mainly introduced to provide enhanced support for wireless networking applications by adding the routing functionality into the entities These type of networks are composed of wireless links most of which are bandwidthconstrained, with dynamically changing multi hop topologies .The main goal of MANETS is to enhance mobility into the realm of autonomous, mobile, wireless domains, where a set of nodes themselves form the network routing infrastructure in an ad hoc fashion. Because the radio transmission range is very less, there is a lot of overhead involved with respect to routing , security in particular This is because the nodes are more prone to failures and compromises in ad hoc networks because of their mobility. Examples of proactive protocols are DSDV,ODMRP,DSR,TORA etc
