Using Context Awareness to Improve Quality of Information Retrieval in Pervasive Computing
Publish-subscribe-query information broker middleware offers great promise to users of pervasive computing systems requiring access to information. However, users of publish-subscribe-query information broker middleware face a challenge in requesting information. The decoupling of publishers and consumers of information means that a user requesting information is frequently not aware of what is available, where it comes from, and when it becomes available.
