Problem statement: Causal ordering is used in Mobile Distributed Systems (MDS) to reduce the non-determinism induced by four main aspects: host mobility, asynchronous execution, unpredictable communication delays and unreliable communication channels. Some causal protocols have been proposed for MDS. All of these protocols in order to ensure the causal(More)
26 27 The paper presents an efficient ∆-causal algorithm for the transmission of real-time continuous 28 media (e.g. audio and video) in distributed systems. The ∆-causal algorithm is oriented to be used in 29 real-time collaborative applications, such as Teleconferece and Teleimmersion. The ∆-causal 30 algorithm ensures causal delivery of messages with(More)
Causal ordering is a useful tool for mobile distributed systems (MDS) to reduce the non-determinism induced by three main aspects: host mobility, asynchronous execution, and unpredictable communication delays. Several causal protocols for MDS exist. Most of them, in order to reduce the overhead and the computational cost over wireless channels and mobile(More)
A cellular network consists of two main components: base stations (BS) and mobile hosts (MH). It is through base stations that mobile hosts can communicate. In order to reduce the causal overhead and the computational cost over mobile hosts, most of the existing protocols for cellular networks ensure causal order at BSs. However, these protocols introduce(More)
LIS1 is one of principal genes related with Type I lissencephaly, a severe human brain malformation characterized by abnormal neuronal migration in the cortex. The LIS1 gene encodes a brain-specific 45kDa non-catalytic subunit of platelet-activating factor (PAF) acetylhydrolase-1b (PAFAH1b), an enzyme that inactivates the PAF. We have studied the role of(More)
—Web Services paradigm is becoming a very powerful architecture for organizations in integrating heterogeneous applications; these provide functionality and form the basis for complex distributed business processes. Open standards make suitable Web Services inter-operable for distributed environments. Collaboration between organizations is crucial in this(More)

The synchronization of continuous media is a key issue in the development of distributed systems, such as videoconference and virtual reality. These services must be carried out in a synchronized manner with different media types, like continuous and discrete media. Due to the unreliable and asynchronous nature of networks, some problems can disrupt the(More)
