Pervasive middleware technology

Pervasive middleware enhances the efficiency of application development and facilitates its running by the reuse of software infrastructure,which is a research hot-spot of pervasive computing nowadays. The paper sums up the design challenges of pervasive middleware,analyzes its key technologies in details based on the classification including context management,middleware self-adaption,self-adaptive oriented services and support mechanisms of self-adaptive software architecture,and introduces the most well-known pervasive middleware projects. At the end,future research directions of this domain are presented.
