In a complex business network finding a supplier can be a very time consuming task. In advanced supply networks like build-to-order supply chains, this task should be carried out under time constraints and under uncertainties both in suppliers and in the orders. The technology of semantic service oriented architectures is aimed to support such tasks, enabling self-organising ...

In today's world of home automation, smart objects are interconnected and participate in the Internet of Things. Being part of a very sensible eco-system, these entities must be secured against various kinds of attacks. Smart home appliances such as light bulbs or window shutters have very low processing power and networking capacities and more often than not lack ...

Nowadays dynamic networks have been growing and have made mobile ad hoc network (MANET). One of the most important tasks in mobile and dynamic environments is service discovery, i.e. how a client can use his service of interest. Context information that show status of entity, play important roles for service discovery. In this paper, we propose a context aware ...

The key features of this design model include support for context-based service discovery and binding, ...

A vast majority of web services exist without explicit associated semantic descriptions. As a result many services that are relevant to a specific user service request may not be considered during service discovery. In this paper, we address the issue of web service discovery given nonexplicit service description semantics that match a specific service request. Our approach to semantic-based ...

Web Service composition has become indispensable as a single web service cannot satisfy complex functional requirements. Composition of services has received much interest to support business-to-business (B2B) or enterprise application integration. An important component of the service composition is the discovery of relevant services. In Semantic Web Services (SWS), service discovery is generally achieved by using service profile ...

In the presence of a variety of service providers that offer web services with overlapping or identical functionality, service consumers need a mechanism to distinguish one service from another based on their own subjective quality of service (QoS) preferences. Typical approaches in this field rely on trusted third parties to monitor the behaviour of service providers and endorse their performance ...

Route and service discovery in wireless multi-hop networks applies flooding or gossip routing to disseminate and gather information. Since packets may get lost, retransmissions of lost packets are required. In many protocols the retransmission timeout is fixed in the protocol specification. In this paper we demonstrate that optimization of the timeout is required in order to ensure proper functioning ...

With the rapid increase in multimedia content and various screen devices, mobile users want to watch content regardless of device type anytime and anywhere, which is called multi-screen service (MSS), performed by service mobility technology.

When an opportunistic network is viewed as a provider of ...

Smart spaces are physical spaces where services provided by Consumer Electronics (CE) devices with varying resource availabilities work together to realize user-specific automated scenarios. These scenarios may be interrupted in case one of the services making up the scenario stops, e.g. due to lack of resources, node failure or leave. Therefore, the user experience is highly dependent on ...

The Internet is moving fast to a new era where million of services and things will be available. In this way, as there will be many functionally-equivalent services for a specific user task, the service non-functional aspect should be considered for filtering and choosing the appropriate services. The related approaches in service discovery mainly concentrate on exploiting constraint ...

The present-day Internet has no separate namespace for host IDs. It uses IP addresses as host IDs, which are in fact locators. This dual role is problematic for mobility, multihoming, security, and routing on the Internet. To solve these problems, research has recently begun on ID/locator split architectures. Some standardization activities based on this concept are also progressing ...

Mobile devices are getting more pervasive, and it is becoming increasingly necessary to integrate web services into applications that run on these devices. We introduce a novel approach for dynamically invoking web service methods from mobile devices with minimal user intervention that only involves entering a search phrase and values for the method parameters. The architecture overcomes technical challenges that ...

Previous efforts towards simplifying Web Service discovery have shown that avoiding some well-known WSDL specification anti-patterns yield quite good results in making more discoverable services. The anti-patterns, however, have been studied with contract-first Web Services, a service construction methodology that is much less popular in the software industry compared to code-first. We study a number ...

Besides this, security measures ...

We extend Constraint Automata by replacing boolean constraints with semiring-based soft constraints. The obtained general formal tool can be used to represent preference-based and similarity-based queries, which allow a user more freedom in choosing the behavior of the service to finally use, among all possible choices. A user states his preferences through a “soft” query, and obtains ...

Furthermore, we observe that using the signal strength commonly provided ...

In hierarchical tree-based routing for service discovery in a MANET, all routes form a tree infrastructure.

Many of the recent sensor network applications assume node mobility. The service provisioning protocol should therefore be designed to be stateless and scalable for continuously changing link states of typical mobile sensor nodes. In this paper, we propose DSDP, Distributed Service Discovery Protocol, for mobile sensor networks. DSDP organizes the network area into hierarchical regions to reduce service update cost. ...

The discovery of suitable services is a crucial, but challenging activity during service-oriented engineering.

With the rapid growth of Web services, service discovery becomes an important and difficult issue. Traditional UDDI-based and WSDL-based methods of service discovery have low precision, and semantic-based service discovery methods are usually inefficient and time-consuming. We observe that social annotations can optimize both precision and efficiency of service discovery. In this paper, we propose a ...

Effective runtime service discovery requires identification of services based on different service characteristics such as structural, behavioural, quality, and contextual characteristics. However, current service registries guarantee services described in terms of structural and sometimes quality characteristics and, therefore, it is not always possible to assume that services in them will have all the characteristics required for effective service discovery. In ...
