| Summary: | 碩士 === 輔仁大學 === 電子工程學系 === 94 === With the characteristics of short range, high-rate, and low-power, IEEE 802.15.3 WPAN enable the isochronous and asynchronous service to meet the requirements of multimedia applications. This paper investigates the isochronous resource allocation problem in IEEE 802.15.3 WPAN. Due to the limited resources of wireless portable device, saving power is one of the most important issues. In this paper, an optimal energy-aware scheduling problem is defined and proved to be NP-complete. Given a set of established isochronous connections and a set of isochronous connections requests, using a minimal number of isochronous bandwidth and minimal energy to service all the connections is attempted. An efficient isochronous resource-allocation algorithm, capable of providing a solution close to the lower bound, is also proposed. Simulation results indicate that the proposed algorithm provides near optimal scheduling to reduce unnecessary switching times and idle time.
