A reliable multicast facility extends traditional point-to-point virtual circuit reliability to oneto-many communication. Such services can provide more efficient use of network resources, a powerful distributed name binding capability, and reduced latency in multidestination message delivery. These benefits wiU be especially valuable in real-time environments where reliable multicast can enabl...

We present a new protocol for reliable data transfer in time-critical applications with zero tolerance for data loss in wireless sensor networks which uses less time and fewer messages in comparison to an established protocol PSFQ. Two key features of our protocol are out-of-sequence forwarding of packets with a priority order for sending different types of messages at nodes and delaying the re...

Grid-based computing environments are becoming increasingly popular for scientific computing. One of the key issues for scientific computing is the efficient transfer of large amounts of data across the Grid. In this poster we present a Reliable File Transfer (RFT) service that significantly improves the efficiency of large-scale file transfer. RFT can detect a variety of failures and restart t...

As grids move from prototypes to testbeds to production infrastructure, grid resource providers are faced with the challenge of delivering reliable services to enable productive use of available resources. On high performance, distributed grids such as the TeraGrid, moving large data sets to, from, and between supercomputing resources requires reliable data management services. The Reliable Fil...

Body sensor networks (BSN) sometimes involve a dynamic and flexible membership of its sensors especially when monitoring of massive users in a disaster scenario. The problem of estranged devices requires a transfer of ownership from one BSN to a different BSN. Based on the models, a BSN has to adapt different mechanisms to address possible threats caused by estranged devices. The objective of o...
