Mobile ad hoc network (MANET) security has become the focus of prolific research efforts. Driven by the unique and considerable difficulties of providing security arising from the dynamic nature of MANETs, many security schemes have been proposed. Rather than trying to encompass the entire field of MANET security, this paper focuses on networks using the popular Ad-hoc On-demand Distance Vector...

In the present scenario, wireless network is being widely used in the area where infrastructure based telecommunication system are unavailable. The mobile ad-hoc network is the infrastructure-less mobile network which has no fixed infrastructure and the nodes can be connected dynamically in an arbitrary manner. The sensor networks are incarnated from ad-hoc networks in which nodes have sensing ...

Abstract Ad hoc network is a special with centerless and dynamic topology. Due to the free mobility of nodes, routing security has been bottleneck problem that plagues its development. Therefore, multi-path QoS (quality service) algorithm based on blockchain by improving traditional AODV (ad on-demand distance vector) protocol (AODV-MQS) proposed. Firstly, chain nodes established in states all ...

Abstract— Wireless Sensor Network is a technological development of small, low cost, low power devices that combine data processing with multiple sensing and the ability to communicate wirelessly. Routing in sensor network is a point of concern for researchers. Many researchers has been proposed various routing algorithm for conserving network resources specially energy consumption due to trans...

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. In mobile ad hoc network, each mobile node acts as a host as well as a router. These nodes communicate to each other by hop-to-hop communication. A number of routing protocols like Ad Hoc On-Demand Distance Vecto...

MANET (Mobile Ad hoc Network) is a collection of nodes interconnected without a fixed infrastructure. For this reason the mobile nodes are resource constraint in terms of energy, storage capacity and processing power. To improve network throughput in MANET routing protocols such as AODV (Ad hoc OnDemand Distance Vector) is proved to be suitable. This is because the AODV protocol is an on-demand...

The Mobile Ad-hoc Networks (MANETs) is an network without any pre-existing infrastructure or the aid of any centralized administration. The topology of this network keeps on changing as the nodes move randomly. There are so many protocols used for such networks. One protocol is Adhoc On Demand Distance Vector (AODV) routing protocol. AODV decrease the routing overhead and hence enhancing the pe...

A mobile ad-hoc network (MANET) is a collection of mobile wireless nodes, which communication to each other without any centralized control. These networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology: thus the call for a strong dynamic routing protocol that can accommodate in such an environment is generated. In addition to this, routing ...

Mobile Ad Hoc Network (MANET) is a distributed and self-organizing network of static and mobile nodes. In MANET, routing protocols are essential to route the packets from source node to the destination node via intermediate nodes. In this paper, performance evaluation of flat routing protocols such as Ad-hoc On Demand Distance Vector (AODV), Destination Sequenced Distance Vector (DSDV), and Dyn...

This research aims to identify the security threats in on-demand routing protocol, AODV for Ad-hoc network. In this context we have extended the AODV protocol with trust and recommendation to secure the network. In AODV, establishment of routing path depends on the faster route request and route reply packets. Rushing attacker exploits such faster traversal activities to attack the network. Rus...
