Enhancements on the loss of beacon frames in LR-WPANs

초록

In beacon-enabled LR-WPANs, the high reliability of beacon frame transmission is required because all transmissions are controlled by the information in the beacon frame. However, the process for the beacon-loss scenario is not carefully considered in the standard. The method proposed in this paper allows a node not receiving a beacon frame to keep transmit its pending frames only within the minimum period of CAP based on the previously received beacon frame while the standard prevents the node from sending any pending frame during a whole superframe. The method is extensively simulated and proven the enhancements on the performances. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
