A Wireless Ad Hoc Network (WANET) is a self configuring network where nodes, connected by wireless links and can move freely by changing its topology constantly. Wireless ad hoc network routing protocols are mainly based on reactive routing that uses minimum hop count. A WANET uses hop count as a parameter to measure the performance of the wireless link between nodes. The wireless links over a long...
The performance of wireless sensor networks (WSNs) degrades due to the presence of faulty sensor node. Therefore, fault node detection is an important problem in WSNs. The conventional fault detection methods where the faulty node is detected by measuring the outlyingness of the sensor data with respect to measured mean is not providing better performance in high noise environment. To overcome that...
A Mobile Ad-Hoc Network is a set of wireless mobile nodes that communes with each other without using any dynamic infrastructure, access point or centralized supervision. In Mobile Ad-hoc network, due to mobility of nodes network topology commutes repeatedly and thus, routing process becomes a challenging task. A selection of routing protocols with varying network circumstances are analyzed and presents...
In Mobile Ad-hoc Network (MANET), routing is the most important issue for communication. Numbers of routing protocols are available for communication in MANET, but optimality is the key issue in routing to improve the performance of MANET. Reactive protocols do not preserve routing information at the network node level, if there is no communication between the nodes. Reverse Reactive protocol determines...
Mobile ad hoc network is coordinated without fixed infrastructure. In the conservative AODV routing protocol, source node always forwards RREQ (Route Request) packet to neighbour for finding path to the destination node. The intermediary (neighbour) node having less lifetime or energy, as well forwards RREQ and lifetime expires after some certain time, i.e. node goes down; it cannot forward RREP (Route...
Mobile Adhoc Networks having self organizing and self configuring network without the need of any centralized base station and physical connections of mobile devices. Mobile ad-hoc network has no fixed topology due to mobility of nodes, interference, path loss and multipath propagation. Therefore, MANET has to need dynamic routing protocols for these networks to function properly for delivering the...
In Mobile Ad hoc network, nodes are connected through a wireless are formed a fast changed network structure and it is a infrastructure less, can be set up anytime, anywhere. The nodes are mobile based on battery operated and nodes have limited battery resources. Routing protocol selection in Mobile Ad Hoc Network is a big challenge, because of its regular topology changes and routing overhead. In...
An ad-hoc network is a self-sufficient collection of mobile nodes that occur to exist within a close nearness in an interval of time. In this paper, a new optimal energy conserving reverse reactive routing protocol has been proposed that computes the shortest path in between any source-destination pair on demand. The approach, unlike other energy conserving reactive protocols, finds loop-free, increases...
In mobile Ad-hoc networks, during the transmission of data, there is a chance of route failure, so that the route rediscovery should be done. Reactive routing protocol determines a route to a specific destination when a particular packet is going to send. Here we propose a reverse reactive routing protocol, based on new route discovery approach, which is used to find an optimal route to the destination...
In Mobile Ad-Hoc Networks (MANETs), mobile devices are equipped with power. In order to utilize this energy equipped devices resourcefully for transmission of data packets, many energy aware routing strategies are followed. As a key note to these routing strategies, the energy aware performance metrics are analyzed on two routing protocols like Ad-Hoc on Demand Distance Vector Protocol (AODV) and...
