Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...

1970s, wireless networks have become increasingly popular in the computing industry. This is particularly true within the past decade, which has seen wireless networks being adapted to enable mobility. There are currently two variations of mobile wireless networks. The first is known as the infrastruc-tured network (i.e., a network with fixed and wired gateways). The bridges for these networks ...

In this paper we propose a distributed intrusion detection system for ad hoc wireless networks based on mobile agent technology. Wireless networks are particularly vulnerable to intrusion, as they operate in open medium, and use cooperative strategies for network communications. By efficiently merging audit data from multiple network sensors, we analyze the entire ad hoc wireless network for in...

A wireless ad hoc network is a notable type of network in which a collection of mobile nodes with wireless network interfaces may form a temporary network, without use of any fixed infrastructure or centralized control. The Dynamic Source Routing protocol (DSR) is a efficient routing protocol explicitly designed for multi-hop wireless ad hoc networks of mobile nodes. A connected dominating set ...

Trust and Trust Management represent the very foundations of Computer and Network Security Protocols enabling all cyber activities. Recent spate of national and global high-impact Cyber Security compromises, threats, vulnerabilities, and exposures leads to fundamental questioning of Trust as the key enabler of all cyber phenomena in the unfolding era of exponentially increasing Distrust. It is ...

Wireless Mobile ad-hoc network (MANET) is an emerging technology and has great strength to be applied in critical situations like battlefields and commercial applications such as building, traffic surveillance. MANET is infrastructure less, with no any centralized controller exist and also each node contain routing capability, Each device in a MANET is independently free to move in any directio...

Ad-hoc wireless networks have been receiving increasing attention in the research community as well as the industry. Ad-hoc wireless networks are distributed systems formed spontaneously without relying on existing infrastructure. It’s formed from wireless mobile nodes which can move around freely; dynamically self-organize into temporary network topologies. Currently there are certain tools av...

A mobile ad-hoc network is an autonomous system of mobile nodes connected by wireless links in which nodes cooperate by forwarding packets for each other thereby enabling communication beyond direct wireless transmission range. The nature of ad-hoc networks makes them vulnerable to attacks especially in routing protocols. Providing security in mobile adhoc networks has been a major issue over t...

Ad Hoc networks does not connected central mode. It is infrastructure less wireless network. Due to high mobility of nodes and multipath propogations topology of this network is dynamically changes. It is self configured network. No. of mobile nodes are connected internally in this network. Mobile Ad Hoc networks protocols are different from other internet protocols of infrastructure based wire...
