Abstract

In the emerging wireless personal area networks (WPANs), one of the active devices in a piconet is designated as a coordinator, which plays a critical roles, e.g., to provide the basic timing for operation of the piconet and manage the QoS requirements/power saving modes. To warrant maintenance of the coordinating function under some unpredictable situations such as sudden power-off or fast movement of a coordinator, it must be seamlessly switched. This paper proposes a new SCS (Seamless Coordinator Switching) scheme to maintain the piconet by selecting a coordinator in the subsequent superframe without incurring the re-initialization overhead.
