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...

Wireless network consist of wireless node without any administration. Due to present of mobility of nodes, the network is easily personated by several attacks. In 1980’s Mobile ad hoc network s have been widely researched ` for many years. Ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies .The infrastructure less and dynamic ...

The IEEE 802.11 MAC protocol is the standard for wireless LANs; it is widely used in testbeds and simulations for wireless multihop ad hoc networks. However, this protocol was not designed for multihop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network, in which multihop connectivity is one of the most prominent f...

In wirelesss ad hoc networks basic network operations are carried out through the cooperation of all available nodes. Due to the inherent lack of a managed infrastructure the nodes of an ad hoc network cannot be considered as trustworthy as in a dedicated infrastructure. Wireless ad hoc networks are thus vulnerable to various exposures threatening the basic network operations like routing and p...

IEEE 802.11 MAC protocol is the standard for wireless LANs, it is widely used in testbeds and simulations in the research for wireless multi-hop ad hoc networks. However, this protocol was not designed for multi-hop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network, in which multi-hop connectivity is one of the m...

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 ...

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...

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is no...

Now a day, security in Mobile Ad hoc Network (MANET) is very important issue. Due to dynamic topology and mobility of nodes, Mobile Ad hoc Networks are more vulnerable to security attacks than conventional wired and wireless network. Nodes of Mobile Ad hoc Network communicate directly without any central base station. That means in ad hoc network, infrastructure is not required for establishing...

With great potentials in a large number of application fields, ad hoc and sensor networks have been undergoing a revolution that promises a significant impact on society. Unlike traditional fixed infrastructure networks, there are no centralized controls over wireless ad hoc networks, which consist of a collection of devices equipped with wireless communication and networking capability. Any co...
