A wireless ad-hoc network is a network which does not use any infrastructure such as access points or base station. Instead, the mobile nodes forward packets to each others, allowing communication among nodes outside wireless transmission range.It is formed spontaneously without any preplanning. Multicasting is a fundamental communication paradigm for group-oriented applications such as secure conferencing, visual broadcasts, military command and control, discussion forums, frequent stock updates, pay per view programs, and advertising. we pres ....etc

A Novel Secure Communication Protocol for Ad Hoc networks
Abstract
An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks.
In this paper, we propose a s ....etc

We propose and analyze a scalable and efficient cluster-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic reconfigurability; we take a cluster-based approach by which group members are broken in to cluster-based subgroups and leaders in subgroups securely communicate with each other to agree on a group key in response to membership change and member mobility events. We show that secrecy requirement for group communication is satisfied. Further, there exists an optimal clus ....etc

People waste many hours driving each day. Although unavoidable, this time can be very boring to motorists.Similar to people taking mass transit who often pass the time socializing with those around them, motorists could benefit from social interactions if they were given broader social opportunities. Unfortunately, existing Multiparty Voice Communication (MVC) systems do not scale to large numbersof users and do not provide adequate access controls. We present RoadSpeak, a scalable MVC system that allows motorists to automatica ....etc

Abstract
In mobile ad hoc networks, due to unreliable wireless
media, host mobility and lack of infrastructure, providing secure
communications is a big challenge in this unique network environment.
Usually cryptography techniques are used for secure
communications in wired and wireless networks. The asymmetric
cryptography is widely used because of its versatileness (authentication,
integrity, and confidentiality) and simplicity for key distribution.
However, this approach relies on a centralized framework
of public key infrast ....etc

Ad-hoc Voice-based Group Communication
The presently existing Multiparty Voice Communication (MVC) systems do not scale to large numbers of users and do not provide adequate access controls. RoadSpeak, a scalable MVC system is presented in this article. With this system, the motorists can automatically join Voice Chat Groups. voice chat message
buffering is made use of in the system to achieve interruptionfree
communication. a RoadSpeak prototype is demonstrated on the N95 smart phones using 3G technology. an MVC simulator is also pre ....etc
