SECURE KEY EXCHANGE AND ENCRYPTION
FOR GROUP COMMUNICATION IN
WIRELESS ADHOC NETWORKS


ABSTRACT

Ad hoc wireless networks is primarily important, because the communication
signals are openly available as they propagate through air and are more susceptible to attacks ranging from passive eavesdropping to active interfering. The lack of any central coordination and shared wireless medium makes them more vulnerable to attacks than wired networks. Nodes act both as hosts and routers and are interconnect ....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

Definition
The term group dynamics implies that individual behaviours may differ depending on individuals' current or prospective connections to a sociological group. Group dynamics is the field of study within the social sciences that focuses on the nature of groups.

Urges to belong or to identify may make for distinctly different attitudes (recognized or unrecognized), and the influence of a group may rapidly become strong, influencing or overwhelming individual proclivities and actions. The group dynamics may also include changes in beha ....etc

Basic Rules and Tips in Group Discussions GD TIPS AND SCORING POINTS



1. Always be the initiator and concluder of the GD then being a participant.

2. But if you are particaipant always try to be the most vianl/key participant.

3. put points firmly and always try to get others support too.

4. if you find that the discussion os going offttrack then never loose an oppurtunity to bring it back to straem this is the best point to score max.

5. try to keep l ....etc

ABSTRACT
A Group Signature schemes as a digital signature
scheme comprises the following:
Today incerasing number of applications demand a
committed bandwidth and high speed for their
transmission but still there is already an urgent need of
secure data transmission . My paper simply define the

FACTS is a concept introduced by Electric Power Research Institute (EPRI), U.S.A.It is actually a group of advanced transmission technologies that rely on high speed, solid-state electronics, rather than electromechanical devices.

By this concept, the apparent impedance of a transmission line is controlled according to certain algorithm. Thus the power system operation is made more reliable, controllable and efficient. The FACTS system is a promising method, which can be implemented into the system for enhancing system stability by damping ....etc

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

EXECUTIVE SUMMARY
The Indian Life Insurance Company has seen a remarkable shift since the time of establishment of the first company, Oriental Life Insurance Company in 1823. At the time of Independence and thereafter, there were more than 200 companies operating in India and not all of them on sound ethical principles. Many factors combined together to prompt the then Government to nationalize the life insurance industry in 1956 to form the Life Insurance Corporation of India.
Insurance sector was once a monopoly ....etc
