– In MANET, ad hoc network is an energetic topology, hosts, and infrastructure less multi-hop wireless ad hoc environment. The efficient node-energy consumption in wireless ad hoc networks is essential as ad-hoc nodes operate with limited battery power. Thus, failure of node in ad hoc network leads to loss of communication in the network and down frequently due to mobility of nodes. It maintai...

A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...

Ad hoc routing protocols have been designed to efficiently reroute traffic when confronted with network congestion, faulty nodes, and dynamically changing topologies. The common design goal of reactive, proactive, and hybrid ad hoc routing protocols is to faithfully route packets from a source node to a destination node while maintaining a satisfactory level of service in a resource-constrained...

VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...

The main application of wireless mobile ad hoc networks is to offer services for situations wherein groups of people come together and share information. The groups of people that use the ad hoc network form some kind of real social network. Thus, real social networks exhibit clustering, the tendency of two individuals who share a mutual friend to be friends themselves. In this paper impact of ...

We present a protocol for managing mobile wireless ad hoc networks. The protocol uses hierarchical clustering of nodes to reduce the number of messages exchanged between the manager and the agents (mobiles). Clustering also enables the network to keep track of mobiles as they roam. ANMP is fully compatible with SNMPv3 and uses the same PDUs (Protocol Data Units) for data collection. The protoco...

A wireless network is a growing technology that allows users to access services and information electronically, irrespective of their geographic locations. Wireless network can be classified in two types: infrastructure network and infrastructure less (ad hoc) network. Mobile ad hoc network is an infrastructure less network without any central coordination point. Mobile ad hoc networks are char...

An ad hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, it may be necessary for one mobile host to want the aid of other hosts in forwarding a packet to its destination, due to the limited range of each mobile host's wireless transmissions. In this paper Ad Hoc...

A Wireless Mobile Ad-hoc Network consists of a number of mobile nodes that temporally form a dynamic infrastructure less network. To enable communication between nodes that do not have direct radio contact, each node must function as a wireless router and potential forward data traffic of behalf of the other. Detecting malicious nodes (Attacker) in an open ad hoc network in which participating ...

An Ad-hoc network is a collection of mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralised administer. Because of limited communication range among mobile nodes in ad-hoc network, several network hopes may be needed to deliver a packet from one node to another node in the wireless network. In recent years, a variety of differe...
