A mobile ad-hoc network is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless links. Due to nodal mobility, the network topology may change rapidly and unpredictably over time. The routing protocols meant for wired network cannot be used for mobile ad-hoc network because of mobility of network. A number of routing protocols like Destination-Sequenced D...

Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. In this article we present a study of secure ad hoc routing protocols for wireless Networks. ...

A mobile ad hoc network is a collection of mobile wireless nodes that can dynamically form a network without necessarily using any pre-existing network infrastructure. In general, routes between nodes in an ad hoc network may include multiple hops. Due to the potential ease of deployment, many practical applications have been conceived for ad hoc networks, including personal area networking, ho...

security term in mobile ad hoc networks has several aspects because of the special specification of these networks. in this paper a distributed architecture was proposed in which each node performed intrusion detection based on its own and its neighbors’ data. fuzzy-neural interface was used that is the composition of learning ability of neural network and fuzzy ratiocination of fuzzy system as...

in a mobile ad hoc network, there are some features such as the ability to exploit multipath effect for information exchange with high reliability and low error rate. dealing with the aggressors and discovering the path in data transmission are of importance. approaching these goals ends in network promotion and efficiency. in this paper, the designed protocol is able to discover multipath fo...

Mobile ad-hoc network is integration of node which is scatterd around the network. Every node in mobile ad-hoc netowk is configured by own, it also decentralized and less secure. Due to mobability properties of mobile ad-hoc network every node in mobile network move around the network. The DDOS attack is the major security in the mobile ad-hoc network. The DDOS attack it generate huge unwanted ...

Providing entity authentication and authenticated key exchange among nodes are both target objectives in securing ad hoc networks. In this chapter, a security framework for authentication and authenticated key exchange in ad hoc networks is introduced. The framework is applicable to general ad hoc networks and formalizes network phases, protocol stages, and design goals. To cope with the divers...

This paper presents a master/slave cellular-based mobile ad hoc network architecture for multihop multimedia communications. The proposed network is based on a new paradigm for solving the problem of cluster-based ad hoc routing when utilizing existing wireless local area network (WLAN) technologies. The network architecture is a mixture of two different types of networks: infrastructure (maste...

A wireless ad hoc network is a decentralized type of wireless network. It is a type of temporary computer-tocomputer connection. It is a spontaneous network which includes mobile ad-hoc networks (MANET), vehicular adhoc networks (VANET) and Flying ad-hoc networks (FANET). A MANET is a network that has many free or autonomous nodes often composed of mobile devices that can operate without strict...

In this paper we discuss about the improvement of security and privacy issues in wireless Ad-hoc network,wireless mesh network and wireless sensor network with the help of routing protocols, authentication and cryptographic tools. Ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. Attacks on ad hoc network routing protocols d...
