AHP-based Master Device Selection Scheme for Pervasive Personal Network
The advancement of mobile communications and small computers bring pervasive personal network closer to reality. To reduce user intervention in the pervasive environment, we proposed a framework to compose a virtual terminal over distributed devices among the pervasive personal network, called UST Since Master Device performs the framework functionality in UST, selecting proper master device plays a vital role in ensuring quality of service especially. In this article we develop a master device selection scheme for UST system based on the Analytic Hierarchy Process (AHP). It also describes the state transitions and message sequences for the scheme. Experimental results show that the proposed scheme can effectively choose the optimum master device under diverse pervasive personal network conditions.
