Aodv Routing Protocol

A Mobile Ad hoc Network (MANET) is a class of wireless mobile nodes that dynamically organize themselves in arbitrary network topologies. Due to mobility of nodes, routing plays an important role in communication and routing protocols are divided into two basic classes: proactive and reactive. AODV is an on demand routing network protocol which is specially design for ad hoc networks. This protocol starts to, only when a certain node claims to send data and is an establish the route efficient ad hoc network routing protocol for data transfer. AODV suffers from the limitation of low bandwidth. In the AODV routing protocol, wherever a link breaks an error message is sent to the source indicating the link failure and further communication is stopped temporarily. This paper proposes an improved AODV routing protocol by including route repair scheme to overcome the link failure problems of its predecessor. In the proposed scheme the data packet is sent through alternate routes instead of dropping it. It is shown through simulation results that the proposed scheme improves data delivery rate.

Abstract With advent of technology MANET is becoming more and more ubiquitous, and so is the vulnerability of such networks to attacks. In this paper, we propose a secure, lightweight, on-demand routing protocol for MANETs. It uses the concept of fidelity to allocate trust to a neighbor, thereby taking the decision whether to send data via that neighbor or not. To combat attacks efficiently new packets like report and recommendation are used. After receiving a few of these packets a node can conclude about the behavior of a node, thereby identifying and blacklisting the malicious nodes. We try to impose bounds for the fidelity with reference to the battery of the node, which restricts a node to increase its fidelity to infinity and become dominant in the network. This protocol not only finds a secure route to transmit data, but also identifies the malicious nodes in the network. Our protocol exhibits high packet delivery fraction, with low normalized routing load and low end to end delay; which has been observed while simulating in GloMoSim platform. We have observed that our protocol performs not only better than other existing secure routing protocol in a malicious environment, but also combats, many attacks which have not been dealt with these protocols.

<p class="Default">Ad hoc networks are mobile wireless networks where each node is acting as a router. The existing routing protocols such as Destination sequences distance vector, Optimized list state routing protocols, Ad hoc on demand routing protocol, Ad hoc on demand multipath routing protocol, Dynamic source routing are optimized versions of distance vector or link state routing protocols.  In this paper, existing protocols such as DSDV, AODV, AOMDV, OLSR and DSR are analyzed on 50 nodes Mobile Ad Hoc network with random mobility. Packet delivery ratio, delay, control overhead and throughput parameters are used for performance analysis.</p>

Demand Routing

Now a days telecommunication technology leads to a rapid growth of number of users, these number of users nothing but number of nodes in MANET.A wireless ad hoc network is a decentralized type of wireless network. The mobility of nodes effect on the performance of the network. Due to mobility of nodes the link breaks number of times which effect on the packet delivery. Therefore to analyze the performance, packet delivery fraction (PDF)can be used. This paper describe the packet delivery fraction of on demand routing protocol AODV and DSR on different terrain areas using GLOMOSIM.

Mobile ad hoc network is a collection of wireless nodes that dynamically organize themselves to form a network without the need for any fixed infrastructure or centralized administration. The network topology dynamically changes frequently in an unpredictable manner since nodes are free to move. Support for multicasting is essential in such environment as it is considered to be an efficient way to deliver information from source nodes to many client nodes. On-Demand Multicast Routing Protocol is a protocol for routing multicast and unicast traffic throughout adhoc wireless mesh networks. ODMRP creates routes on demand so they suffer from a route acquisition delay,although it helps reduce network traffic in general. In future this  results will be compared with AODV and FSR protocol and ODMRP performs better as compared with AODV and FSR protocol.
