Wireless sensor networks are application specific,data centric networks where different applications run on deployed network. Each application interprets the underlying sensor network differently and each changing event has different effect on running applications.In this paper we have proposed context aware middleware architecture called as 'MidSen'. This architecture bridges the gap between multiple...
There have been numerous nanowire crossbar architectures proposed till date and they are envisioned as clock-driven. To deal with numerous issues caused by clocking, a new asynchronous architecture based on Null Convention Logic (NCL) has been recently proposed, resulting in the removal of the clock circuit overhead from the crossbar architecture. The proposed architecture is easier to be manufactured...
Grid is a collection of distributed computing resources that performs tasks in co-ordination to achieve high-end computational capabilities by dividing a given task into sub-tasks. Each sub-task could be large and run for several hours or days on a number of grid nodes. If a sub-task fails to complete even on a single site, all the computations should be performed again. In scalable distributed systems,...
Business processes are event-driven and required set of tasks to be executed to fulfill the goal. Event-driven business process model by representing process as conceptual process flows. Business process required composition of services and execution of services as per the event. Events are responsible to change the state of process so we can model the business process based event and state. Web services...
There have been numerous nanowire crossbar architectures proposed till date, although all of them are envisioned to be synchronous (i.e., clocked). The clock is an important part in a circuit and it needs to be connected to all the components to synchronize their operation. Considering non-deterministic nature of nanoscale integration, realizing them on a nano wire crossbar system would be quite cumbersome...
The rapid progress of Information and Communication Technology has dissolved many technical and social barriers. Publishing, storing, updating and even accessing information through wireless devices is no longer a significant problem. As information increases, finding, sharing and integrating information from distributed heterogeneous sources become a major issue. The challenge is no longer in providing...
