Rateless codes are a class of codes without a predefined number of encoding symbols. Fountain codes are the first such codes. Luby Transform codes, designed by Michael Luby, are examples of these codes. The accepted and efficient decoding algorithm for these dense bipartite codes is the belief propagation (BP) algorithm as opposed to Gaussian elimination(More)
Ubiquitous service provision demands a flexible, low complexity and small foot-print platform that can perform in heterogeneous devices. In this paper, we describe the deployment of JADE as a ubiquitous electronic market platform for trading of adaptation services. We then statistically measure JADE's transport protocol efficiency over wireless WAN networks(More)
Ubiquitous services have gained increasing attentions in the area of mobile communication aiming to allow service access anywhere, anytime and anyhow while keeping complexity to a minimum for both users and service providers. Ubiquitous environment features a wide range and an increasing number of access devices and network technologies. Context-aware(More)
