In this paper, we discuss security issues and their current solutions in the mobile ad hoc network. Owe to the vulnerable nature of the mobile ad hoc network, there are numerous security threats that disturb the development of it. We first analyze the main vulnerabilities in the mobile ad hoc networks, which have made it much easier to suffer from attacks than the traditional wired network. The...

Mobile ad-hoc networks are typically very dynamic networks in terms of available communication partners, available network resources, connectivity, etc. Furthermore, the end-user devices are very heterogeneous, ranging from high-end lap-tops to low-end PDAs and mobile phones. Traditionally, middleware is used to abstract from this heterogeneity and enable the application programmer to focus on ...

In this paper, we give a brief overview of several recent proposals that address the problem of group key distribution in secure multicasting over mobile ad hoc networks. We discuss the requirements and challenges raised from multicast in ad hoc networks in general and group key distribution over mobile ad hoc networks in particular. We also give the analysis of each proposal in terms of effici...

A Mobile Ad-hoc Network builds the self-configuring wireless network with compilation of nodes and these mobile nodes with dynamism correspond to other nodes without any centralized infrastructure. Mobile nodes be similar to as router and forwards packets to other nodes in the network. A wide range of protocols are involved in Mobile Ad hoc Network for communicating and transferring of packets ...

With the spread of wireless technology, mobile ad hoc networks is getting increased attention in recent years. In mobile ad hoc networks, network topologies dynamically change because of node mobility. Thus, it is important to design an algorithm that has strong stability against frequent topology changes. Attractor selection is one of the biologically inspired approaches that have strong stabi...

In this position paper we argue that applications for the communication between vehicles do not require the functionality typically offered by mobile ad-hoc-networks or wireless sensor networks. Consequently the name Vehicular Ad-Hoc Network (VANET) is a misnomer leading practitioners and researchers astray. In order to make our point we briefly outline the characteristics of Mobile Ad-Hoc Netw...

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...

Mobile Ad-Hoc Networks (MANETs) are becoming increasingly popular as more and more mobile devices find their way to the public, besides ―traditional‖ uses such as military battlefields and disaster situations. They are being used step by step in every-day stages. With this increased usage of MANETs comes the need for making the networks secure as well as efficient, something that is not readily...

The general field of mobile ad hoc networking is still in its infancy. Particularly, the challenge of providing Quality-of-Service (QoS) support for ad hoc networks is an open problem and remains relatively uncharted territory. Providing a complete QoS solution for the ad hoc networking environment requires the interaction and cooperation of several components. These components include: (1) a Q...
