-Mobile Ad Hoc Network is a collection of mobile nodes that communicates with each other over wireless links. MANETs are dynamic and self configuring networks with self-administration. Due to mobility of nodes in MANETs which results in frequent and arbitrarily changes in network topology, providing quality of service of multicast routing in MANETs is a challenging and critical task. Different ...

Presently, mobile ad hoc networks (MANETs) are being used extensively in the defense, private, domestic, etc. fields and each of these emulates a personal area network (PAN). A MANET does not require any infrastructure; moreover, it can behave as a mobile network. These features have boosted the popularity of MANETs in the community. As more and more fields become dependent on MANETs, the syste...

The infrastructure-less and the dynamic nature of mobile ad hoc networks (MANETs) demands new set of networking strategies to be implemented in order to provide efficient end-to-end communication. MANETs employ the traditional TCP/IP structure to provide end-to-end communication between nodes. However, due to their mobility and the limited resource in wireless networks, each layer in the TCP/IP...

-In this paper protocols for group key distribution are compared and evaluated from the point of view of Mobile Ad Hoc Networks (MANETs). A MANET is a collection of wireless mobile nodes, communicating among themselves over possibly multihop paths, without the help of any infrastructure such as base stations or access points. So the need to render those networks as autonomous and secure as poss...

Mobile Ad Hoc Networks (MANETs) are susceptible to a variety of attacks that threaten their operation and the provided services. Intrusion Detection Systems (IDSs) may act as defensive mechanisms, since they monitor network activities in order to detect malicious actions performed by intruders, and then initiate the appropriate countermeasures. IDS for MANETs have attracted much attention recen...

In recent years, the security issues on MANET have become one of the primary concerns. MANETs rely on the cooperation of the nodes participating in the network to forward packets for each other. Therefore, MANET routing protocols are more vulnerable than routing protocols in wired networks. Because of unique features of MANETs, existing security mechanisms,

In this paper, we present a quality of service (QoS) architecture for supporting real-time data transmission in mobile ad hoc networks (MANETs). The QoS architecture includes a QoS transport layer, QoS routing, queue management and a priority MAC protocol. Through simulations, we find that the QoS architecture reduces packet delay and greatly improves the quality of realtime video streams in MA...
