“…This is complementary to our work, which focuses on resource awareness, where reconfiguration in the opportunistic overlays is based on nodes' physical locations and the underlying physical network topology. Similar to the approach in [22], the topology used in [23] must remain acyclic, whereas the opportunistic overlay approach supports general broker overlay topologies.…”

“…In addition, the approach assumes a tree-based topology between dispatchers, which makes it hard to achieve robustness, since a single link failure partitions the tree. Another approach to dynamic broker network configuration is described in [23]. The idea is to place 'close' to each other brokers that manage similar subscriptions.…”

Abstract. Current content-based publish/subscribe systems assume network environments with stable nodes and network topologies. For mobile environments, one resulting problem is a mismatch between static broker topologies and dynamic underlying network topologies. This mismatch will result in inefficiencies in event delivery, especially in mobile ad hoc networks where nodes frequently change their locations. This paper presents a novel middleware approach termed opportunistic overlays, and its dynamically reconfigurable support framework to address such inefficiencies introduced by node mobility in publish/subscribe systems. The opportunistic overlay approach dynamically adapts event dissemination structures (i.e., broker overlays) to changes in physical network topology, in nodes' physical locations, and in network node behaviors, with the goal of optimizing end-to-end delays in event delivery. Runtime adaptations include the dynamic construction of broker overlay networks and changes of mobile clients' assignments to brokers. Experimental results demonstrate that the opportunistic overlay approach is practically applicable and that the performance advantages attained from the use of opportunistic overlays can be substantial.

“…Consumers with few resources can limit their input network traffic by registering their interests for receiving a special type of massage [1]. 4. Determining route of messages based on the interests of consumers, causes messages which the recipient's interests for receiving them are not recorded in the system not to be published and this will result in system efficiency [5].…”

The main component of electronic commerce (E-commerce) is the exchange of documents and messages. In the field of commercial messages standardization, the ebXML framework offers the valid standard for message modeling.Due to the importance of standardization ebXML framework in E-commerce, creating more facilities, in the ebXML messaging is so important. Today, the exchange of messages within the ebXML framework uses explicit addressing, in which, the message ultimate recipient is determined based on message producer partner and the information existed in collaboration agreement. In case of explicit addressing Use, among the messages that are reached by the partners in the business process, only a few of them may be appropriate to the needs of the recipient and as a result the recipient is forced to discard some of them. Due to releasing a large number of relatively high-volume messaging in system, not only the bandwidth consumption will rise, but it also slows down the message precision regarding to the message received by the partner that is appropriate to its needs or not. The purpose of this paper is providing a method in order to convert an explicit addressing to the implicit addressing for ebXML messages. The proposed method is based on an algorithm called "Rendezvous", that's one of the algorithms which have been widely used in networks based on contents and specifically in publish/subscribe systems. At the end of work though, bandwidth parameters, speed and precision in both traditional ebXML messaging method and the proposed messaging method are compared.
