Scalability is an important issue in the construction of distributed systems. Shared object spaces provide an elegant and easy-to program abstraction for building applications. However, existing shared object spaces have been realized at the cluster level. Use of centralized components, lack of effective failure handling mechanisms, lack of efficient object(More)
Current mobile and distributed applications are being developed using J2ME, J2EE, CORBA, DCOM, etc. Developing applications for distributed and mobile systems is a tedious process, because the applications in these systems are open for change in requirements. So providing a language support for application development in open systems is vital.(More)
With the advancement of technology in micro-electronics and wireless communication, small miniature devices called sensor nodes can be used to perform various tasks by forming themselves in to wireless sensor networks. In Wireless Sensor Networks(WSN), event detection is one of the main requirements for most of the applications. An event can be a simple(More)
SUMMARY In the conventionalobject model, encapsulated objects interact by messages that result in method invocations on the destination object. A message is delivered directly at the destination object. As a result of the direct deliveries, the message control code performing intermediate message manipulations cannot be abstracted out separately from the(More)
—The practice of computing across two or more data centers separated by the Internet is growing in popularity due to an explosion in scalable computing demands and pay-as-you-go schemes offered on the cloud. While cloud-bursting is addressing this process of scaling up and down across data centers (i.e. between private and public clouds), offering service(More)
Sybil attack is one of the most challenging problems that plague current decentralized Peer-to-Peer systems. In Sybil attack, a single malicious user creates multiple peer identities known as sybils. These sybils are employed to target honest peers and hence subvert the system. In this paper, we propose a novel solution that enables all honest peers to(More)
—Parallel computing on interconnected workstations is becoming a viable and attractive proposition due to the rapid growth in speeds of interconnection networks and processors. In the case of workstation clusters, there is always a considerable amount of unused computing capacity available in the network. However, heterogeneity in architectures and(More)
