Abstract: As technologies required for collaborative computing grow, there are business collaborations among companies carrying out related business. The communication and interactions across the companies has become a common phenomenon. In order to create and sustain this kind of business collaborations, specialized methods or techniques are required. In this paper we propose concept of bridging socially enhanced virtual communities. It is achieved by discovering present relevant businesses and prospective business alliances by developing a semi-automated approach. The architecture of the proposed system is compromising of human activities and also automated activities and it is essentially a service oriented system. For the purpose of bringing the previously separated groups and also finding new relevant groups we introduced broker discovery concept that makes use of techniques and metrics pertaining to interactive mining. The empirical results revealed that the proposed system is effective when tested with test bed which is based on distributed technology such as web services.

Abstract: In this paper specialize in the detection of the compromised machines during a network that are concerned within the spamming activities. In this paper, considering the matter in unsought spam e-mail's wherever crucial information's are divided to assure data confidentiality and integrity. The replicas of divided shares are dynamically allotted to boost recital. Heuristic search minimizes the spam access in Zombies. During this paper, Network official examines unsought e-mail by mistreatment the heuristic search, and reportable to the tip user. Once checking the activities beside IP address, the unsought e-mail is blocked that are originated by Zombies. Index term-Zombies, spam, secure information, secret sharing, and heuristic.

Abstract: The science and technology is developing day by day leading to expand and forcing to reshape our living standards. The main aspects leading to deployment of a wide array of wireless and mobile networks are advances in miniaturization, low power circuit design and development in radio access technologies and increase in user demand for high speed internet access. The varying wireless technologies are driving today's wireless networks to become heterogeneous, ie., the network comprised of two or more different access network technologies. Heterogeneous networks have created many challenges such as mobility management, handoff, resource management, location management, providing QoS, security and pricing. Switching between heterogeneous networks requires seamless vertical handoff. The selection of parameters plays an important role in the decision of vertical handoff. The parameters like bandwidth, signal strength, velocity, power consumption, throughput, cost, user preferences and network load are considered during vertical handoff. In this paper, the vertical handoff parameters of the existing work are critically ascertained and presented in a tabular format for identifying the important parameters. A dynamic, adaptive and efficient approach is required to implement the vertical handoff mechanism in next generation heterogeneous wireless networks to produce an effective service for the user by considering dynamic and non dynamic parameters.
