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...

Mobile ad-hoc network is a collection of mobile nodes that are connected wirelessly forming random topology through decentralized administration. In Mobile ad-hoc networks, multicasting is one of the important mechanisms which can increase network efficiency and reliability by sending multiple copies in a single transmission without using several unicast transmissions. Receiver initiated mesh b...

Mobile ad hoc networking is a challenging task due to the lack of resources reside in the network as well as the frequent changes in network topology. Although lots of research have been done on supporting QoS in the Internet and other networks, they are not suitable for mobile ad hoc networks and still QoS support for such networks remains an open problem. In this paper, we provide a brief ove...

Security is a major concern in wireless technology and this work deals with security in wireless mobile ad-hoc network by using Novel IDS in Open Shortest Path First (OSPF) routing protocol. We are bounding wireless mobile ad-hoc network nodes to getting updates from unknown or unwanted nodes on the same network through routing table; we are using a Novel intrusion detection technique with the ...

A mobile ad-hoc network is an autonomous network that can be formed without any established infrastructure, where nodes can move arbitrary in the topology with variation of speed and trajectory. Mobile Ad-hoc Networks prove to be the best fit for various applications like Military operations, Flood affected areas, Remote area etc. Ad-hoc Networks are limited with energy and generally more vener...

In the emerging world, in a resource constrained network like mobile ad hoc network, the mobile agent is becoming a favorable option for creating applications like service discovery, network discovery, automatic network reconfiguration etc. due to its astonishing features like autonomy and mobility. The joint venture of the two technologies mobile agent and mobile ad hoc network is contributing...

This paper presents Chameleon, a novel anonymous overlay network for mobile ad hoc environments. As far we know, Chameleon is the first lowlatency anonymous overlay network applied in a mobile ad hoc setting. It was designed with the special characteristics of mobile ad hoc networks in mind, such as limited battery lifetime, user mobility and vanishing nodes. In this paper, we also evaluate Cha...

Mobile Ad Hoc Network (MANETs) is collection of mobile/semi mobile nodes with no existing pre-established infrastructure, forming a temporary network. Mobile Ad hoc Networks are highly dynamic networks. Quality of Service (QoS) routing in such networks is usually limited by the network breakage due to either node mobility or energy depletion of the mobile nodes. Another issue that effects the Q...

A mobile ad hoc network (MANET), is a self-configuring network of mobile devices connected by wireless links. The Ad hoc networks are a new wireless networking paradigm for mobile hosts. Wireless adhoc network is autonomous, infrastructure less and may be mobile depending on its type of application. Secure transmission of information in wireless adhoc environment is an important concern. In thi...

A Congestion control is a key problem in mobile adhoc networks. The standard TCP congestion control mechanism is not able to handle the special properties of a shared wireless channel. Many approaches have been proposed to overcome these difficulties. ideas and show their interrelations. mobile agent based congestion control Technique routing is proposed to avoid congestion in ad hoc network. S...
