Real-time information dissemination is essential for the success of key applications such as transportation management and battlefield monitoring. In these applications, relevant information should be disseminated to interested users in a timely fashion. However, it is challenging to support timely information dissemination due to the limited and even time-varying network bandwidth. Thus, a nai...

A key problem to allowing distributed operating systems to effectively utilize resources is the problem of disseminating resource information. Traditional solutions whilst scalable only provide limited information and impose a fixed overhead on the system. In this paper we present a novel technique for propagating information which allows the distance travelled to vary with the workload of the ...

In this paper, we study a broadcast problem in directed trees. This problem is motivated by the task of implementing broadcast and multicast requests in computer systems with networks that utilize circuit routing schemes such as wormhole routing or virtual cut through routing as opposed to store and forward routing. Examples of such systems include the Intel Paragon and the NCUBE-2. The problem...

Future smart environments will be characterized by multiple nodes that sense, collect, and disseminate information about environmental phenomena through a wireless network. In this paper, we define a set of applications that require a new form of distributed knowledge about the environment, referred to as non-uniform information granularity. By non-uniform information granularity we mean that t...

We propose an information push model for information dissemination to mobile users, called the dynamic channel model, which is a set of extensions to the conceptual models developed for information channels that capture mobility-specific requirements. Dynamic channels are used for filtering and setting update order priorities for the information that users intend to monitor, which depends on th...

The amount of data output into our environment is increasing each day, and the development of new technologies constantly redefines how we interact with this information. It is therefore necessary to control the different ways information is diffused. To do so, a four-step data dissemination methodology in the framework of the Supply Chain Management (SCM) is introduced in this paper. On the on...
