SOC is different from the traditional Grid model (including P2P desktop Grid) in the resource consumption manner. Grids generally assume exclusive resource usage to ensure user QoS. The problem of job scheduling in Grids is usually categorized as a multiprocessor scheduling (MPS) problem (a kind of combinatorial optimization problem), which has been proved to be […]

Visual cryptography (VC) is a secret sharing scheme, based on black and white or binary images. Secret images are divided into share images which, on their own, reveal no information of the original secret. Shares may be distributed to various parties so that only by collaborating with an appropriate number of other parties, can the […]

Network Our research aims at providing a scalable, reliable, and robust approach for web service discovery. An overview of web service discovery. Service-oriented Computing (SOC) is emerging as a new paradigm for developing distributed applications. Service discovery, among the most fundamental elements of SOC, is critical to the success of SOC as a whole. Traditional […]

The wireless channel is impaired by random fluctuations in signal level across space, time, and frequency dimensions known as fading. This signal fluctuation (also called diversity) can be exploited by the use of multiple transmissions/ receptions distributed across time or space with appropriate encoding to enhance and stabilize the signal level at the receiver. Such […]
