Ad hoc Network is a temporary network and these networks nodes are free to move about and organize themselves into a network. These nodes change position frequently. A Reactive (on-demand) routing strategy is a popular routing category for wireless ad hoc routing. The design follows the idea that each node tries to reduce routing overhead by sending routing packets whenever a communication is r...

A mobile ad hoc network (MANET) is a wireless network that uses multi-hop peer to peer routing. A user can move anytime in an ad hoc scenario and, as a result, such a network needs to have routing protocols which can adopt dynamically changing topology. To accomplish this, a number of ad hoc routing protocols have been proposed and implemented such as, Ad hoc On-Demand Distance Vector routing (...

Adhoc on demand distance vector routing protocol(AODV) is specially designed for mobile adhoc networks with reduced overhead using Expanding Ring Search technique. But energy consumption should also be considered in MANET due to battery constrain of the nodes. In this paper, we choose an energy efficient route discovery process for AODV based on Expanding Ring Search(ERS). We want to saves ener...

In Vehicular Ad Hoc Networks (VANETs), the node mobility leads to network topology changed frequently. Due to the vehicle movement, the limited wireless resources and channel fading, the routing protocols in Mobile Ad Hoc Networks MANETs are not suitable for VANETs. In this paper we propose a new multipath route protocol based on Ad hoc On-Demand Distance Vector Routing (AODV) for adapting VANE...

The communications inside MANETs usually show frequent disruptions due to changes in topology and the condition of having a shared physical channel. It is necessary to implement a mechanism to maintain connectivity and ensure Quality of Service (QoS). In this paper we introduce a route recovery mechanism for a QoS routing protocol called AQA-AODV (Adaptive QoS-Aware AODV) which is an extension ...

ABSTACT Vehicular Ad-Hoc network is a type of Mobile ad-hoc Networks, vanet help in developing communication between near vehicles and between vehicles and roadside equipment. The paper aims to investigate the performance of the routing protocol in vanet by using tcp variants that is tcp reno, tcp new reno and tcp tahoe.In the performance evaluation two different routing protocols On-Demand Dis...

With the dawn of Internet Things (IoT), interconnected things and smart applications have significantly reduced human intervention in accomplishing tasks. Yet, due to its openness, heterogeneity, limited resources extensiveness, it suffers from several issues such as lesser capacity links, energy consumption, resource optimization etc. Routing packets constrained environment is yet challenging....

The Ad hoc On-demand Distance Vector (AODV) routing protocol [6] allows the nodes in a Mobile Ad hoc Network (MANET) or a Wireless Mesh Network (WMN) to know where to forward data packets. Such a protocol is ‘loop free’ if it never leads to routing decisions that forward packets in circles. This development mechanises an existing pen-and-paper proof of loop freedom of AODV [4]. The protocol is ...

Security is an essential requirement in mobile ad hoc networks to provide protected communication between mobile nodes. MANETs are vulnerable to various attacks; black hole is one of the possible attacks. Black hole is a type of routing attack where a malicious node advertise itself as having the shortest path to all nodes in the environment by sending fake route reply. We attempt to focus on a...
