A Quality Driven Approach for Provisioning Context Information to Adaptive Context-Aware Services

A context broker federation for QoC-driven selection of cloud-based context services

“…Given that context consumers do not normally have the capabilities to negotiate, manage, and monitor QoC, they delegate management tasks, such as selection of appropriate context providers and Context Level Agreement (CLA) negotiation, to the Context Broker. The architecture of the Context Broker and the CLA negotiation process have been described in our previous work [27]. The CLA specifies the context information and the agreed upon level of QoC that the context-provider shall deliver.…”

e-Business Challenges and Directions: Important Themes from the First ICE-B Workshop

“…This paradigm of the customer relationship where the customer feels like they are they only one, or the most important customer of a company, is called "N = 1" [133]. To adopt this aspect to m-Business, and to create value for the customer, m-Services should be context aware and rapidly change to address user needs and environment [11]. One important context would be the current location of a user.…”

“…Since consumers with less technical experience usually describe their needs by giving concrete examples, involving them can provide producers with more concrete and straightforward information about the expected product [185]. The framework and the goals of existing and future application usage can be better determined if explained with concrete examples using simple language [11]. Application designers will then be able to transform those requirements into technical language, and thus implement e-Business applications with fewer errors.…”

“…So, e-Business is trying to spread into every corner of the Internet, such as: blogs, wikis, portals, and social networks -in other words, e-Business must now be managed, or business will find the well-known phenomenon of "scope creep" to severely impact profitability [135]. If managed properly, consumers stand to gain many benefits; for example: a) personalized products [15], [181], b) better and simpler services [11], c) more intuitive and natural user interfaces [16], d) novel ways to transact [116] and e) application behavior sensitive to the user's current context [104].…”

“…This aspect of context awareness is very important for the private use of application services and even more for business use (e.g., for mobile sales and service representatives or mobile workers). Thus, the quality of the context information plus the analytical combination to come to the right conclusion about the user's current situation can be seen as one determining factor in the adoption process of application services [11]. Summing up, one direction in mobility will be that application services are using and combining several context services so that they can exactly adapt their services to the current context and situation of a user and offer appropriate service.…”
