In pervasive computing, the internal requirements of multi-task concurrent real time system are analyzed, and the relevant allocation model and optimization principle are given. With respect to the features of genetic algorithm, a task-driven service allocation mechanism is designed and the experimental results demonstrate that the mechanism is effective and feasible.
Rough sets theory is applied to the service matchmaking algorithm for pervasive computing. The relevant service matchmaking algorithm model and method are presented in the paper. The decision system is built on the basis of the sample data from service resources. The evaluation indexes for service matchmaking are taken as the attributes to find out the important attributes that reflect the essential...
The hierarchy of task-computing and the decomposition strategy of complex task are analyzed according to the characteristics of task-computing in pervasive environment. The architecture relies on the semantic representation of service and content, however, the semantic representation is based on shared ontology. It can not only improve the accuracy and recall, but also realize the functions such as...
