“…Another distinction from the work of Baldoni et al is that while SIENA is a content based Publish/Subscribe system, Web service Publish/Subscribe specifications adhere to a topic based scheme. (Lekova et al, 2007) have created a distributed event notification system (DENS) for MANETs. They developed a fuzzy logic based subscription language allowing expressive subscriptions and sophisticated event filtering.…”

In scenarios such as search-and-rescue operations, it may be required to transmit information across multiple, heterogeneous networks, often experiencing unreliable connections and limited bandwidths. Typically, there will be traffic within and across radio networks, as well as back to a central infrastructure (e.g., a police command post) when a reach-back link is available. This implies that using Publish/Subscribe is advantageous in order to reduce network traffic, and that store-and-forward capabilities are required to handle the instability of radio networks. At the same time, it is desirable to use commercial software based on standards as far as possible, in order to reduce cost and development time, and to ease interconnection of systems from different organizations. We therefore propose using SOA based on Web services in such scenarios. Indeed, Web services are targeted at stable, high-speed networks, but our work shows that such usage is feasible. In this paper, we add Publish/Subscribe functionality to standard, unmodified Web services through the use of our prototype middleware solution called the Delay and Disruption Tolerant SOAP Proxy (DSProxy). In addition to the ability to make Web services delay and disruption tolerant, the DSProxy enables SOAs in scenarios as described above. The DSProxy has been tested in field trials, with promising results.

“…Equ.10 shows the defuzzification functions for f. The defuzzification method uses the center-of-maximum (CoM), where x i is the input, p is the number of rules, and f is the output [19]. Mamdani type fuzzy controller uses a range of input variables for making membership function [20] as shown in Fig.…”

Link breakage is of high probability in mobile wireless adhoc networks because of highly dynamic nature of MANET. This is because of limited transmission range, mobility and limited battery power. It becomes difficult to maintain continuous links in the networks. In AODV, node generates a RERR message for the given destination when it noticed that a link breakage has taken place. This hampers the continuity of the link and results in link breakage, in loss of some packets and increase in delay and overhead. Link breakage, delay and packet loss is not tolerable in real time communication and loss of packets, more overhead is not tolerable in non real time communication. So AODV is modified to cope up with these problems. An algorithm using cross layer approach is proposed which helps in maintaining the continuity of the network resulting in more throughput, less delay, less overhead and less battery power consumption which can be used for both real time and non real time communication.

“…The idea that a publication has a degree of relevance to a subscription, instead of simply being matching or nonmatching, is not a new one [22,24,23,8,31,20]. Liu and Jacobsen [22,24,23] introduced the degree of relevance in publish/subscribe systems.…”

Existing content-based publish/subscribe systems are designed assuming that all matching publications are equally relevant to a subscription. As we cannot know in advance the distribution of publication content, the following two unwanted situations are highly possible: a subscriber either receives too many or only few publications. In this paper we present a new publish/subscribe model which is based on the sliding window computation model. Our model assumes that publications have different relevance to a subscription. In the model, a subscriber receives k most relevant publications published within a time window w, where k and w are parameters defined per each subscription. As a consequence, the arrival rate of incoming relevant publications per subscription is predefined, and does not depend on the publication rate. Since all relevant objects (i.e. publications in our case) cannot be kept in main memory, existing solutions immediately discard less relevant objects, and store only a small representative set for subsequent delivery. In this paper we develop a probabilistic criterion to decide upon the arrival of a new object whether it may become the top-k object at some future point in time and should thus be stored in a special publications queue. We show that by accepting typically very small probability of error, the queue length is reasonably small and does not significantly depend on pub- *
