Proactive Coordinator Appropriation (PCA) Scheme for Wireless Personal Area Networks

In the event of PNC failure, the event of PNC leaving a piconet without a proper handover procedure, it is critical to have a scheme that allows one of the PNC capable DEVs to take over the role of PNC to minimize the interruption of services. A new proactive coordinator appropriation (PCA) scheme is proposed to prevent piconets from collapsing in the event of PNC failure. PCA is an efficient and reliable scheme that detects PNC failure in a timely manner, while minimizing the probability of false detection. An analytical comparison of PCA with the existing schemes of similar functionality is provided.
