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

abstract is :

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

Bluetooth Ad Hoc Networking

Abstract :

Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices. The problem concerns the assignment of the roles of master and slave to each node so that the resulting MANET is connected. In this Seminar we have introduce two novel protocols for forming connected scatternets. In both cases, the resulting topology is termed a bluetree. We also address the problem of determining an opt ....etc

Abstract—We investigate the communication range of the nodes necessary for network connectivity, which we call bidirectional connectivity, in a simple setting. Unlike in most of existing studies, however, the locations or mobilities of the nodes may be correlated through group mobility: nodes are broken into groups, with each group comprising the same number of nodes, and lie on a unit circle. The locations of the nodes in the same group are not mutually independent, but are instead conditionally independent given the location of the group. W ....etc

“GROUP AWARENESS IN BLUETOOTH”
Outline
GROUPING
Grouping is a fundamental human cognitive
process affecting on group awareness.The cognitive. The aspects of grouping are called “Gestalt's law”.
E.g. similarities between location,distance and connection.
 Context Awareness
 Task,Goal,Usability
End user of the service has some goals when using a bluetooth service or device.

Abstract—Given a data point set , a query point set , and an integer , the Group Nearest Group (GNG) query finds a subset ( ) of points from such that the total distance from all points in to the nearest point in is not greater than any other subset ( ) of points in . GNG query is a partition-based clustering problem which can be found in many real applications and is NP-hard. In this paper, Exhaustive Hierarchical Combination (EHC) algorithm and Subset Hierarchial Refinement (SHR) algorithm are developed for GNG query pr ....etc
