Mobile ad hoc networks are collection of mobile devices connected by wireless links to perform some computational tasks. This temporary arrangement does not have any infrastructure hence lacking in permanent source of energy. To fulfill this requirement these independent mobile devices are entirely dependent on battery power. The aim of this paper is to design and evaluate the performance of an...

AODV (Ad hoc On Demand Vector) is a reactive routing protocol in wireless mobile ad hoc network (MANET). AODV is accepted because of its capacity to adjust quickly in dynamic system environment with least overhead and small management packet size. The adhoc networks are all that much helpless against Dos attacks on the network layer. Blackhole and Grayhole attacks are the far reaching attacks o...

The Ad Hoc on demand distance vector (AODV) routing protocol is designed for mobile ad hoc networks (MANETs). AODV offers quick adaptation to dynamic link conditions; it is characterized by low memory overhead and low network utilization. The security issues related to the protocol remain challenging for the wireless network designers. Numerous schemes have been proposed for establishing secure...

AODV protocol is an on demand reactive protocol, which exhibits congestion during high mobility and multiple data packet stream to a common destination. This may result in decaying the performance of AODV. The proposed modification is aim controlled congestion by applying efficient local route repair method. When the link failure is detected at intermediate node, a help message has broadcasts t...

An ad hoc wireless network is highly impacted by the dynamic stochastic process of its underlying links which leads to link breaks during data transaction. Hence, to provide uninterrupted data transaction many routing algorithms have link recovery and maintenance procedures to minimize the loss of data. However these procedures do not guarantee reliable data transmission in some special applica...

Vehicular Ad-Hoc Networks (VANETs) have recently gained considerable attention from both research and industry communities. One of the challenges posed by the study of VANETs is the definition of routing protocols design. In this paper, a realistic simulation environment is developed based on Mobility model generator for Vehicular networks (MOVE) and Network Simulator (NS2). The performance of ...

A Mobile Ad-hoc network (MANET) consists of a number of mobile wireless nodes, among which the communication is carried out without having any centralized control. MANET is a self organized, self configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The mobile nodes can receive and relay packets as a router. Routing is a critical issue and an efficient r...

This paper evaluates the performance of two prominent on-demand routing protocols, which are Dynamic Source Routing (DSR) and Ad Hoc On-Demand Distance Vector Routing (AODV) for wireless sensor networks. Results obtained from simulations demonstrates that even though DSR and AODV share a similar on-demand behavior, the differences in the protocol mechanics can lead to significant performance di...

MANETs (Mobile Ad Hoc Networks) are wireless networks with characteristics such as self organizing or autonomous, multi-hop and resource constrained. These resource constraints includes limited power, bandwidth etc. which in turn increases the difficulty in MANETs routing. The problem space includes route break, control overhead, limited energy etc. Ad-hoc On Demand Distance Vector (AODV) is th...
