The response time is one of the main constraints in bluetooth synchronization and message transfer. This paper provides a novel approach for calculating a probabilistic worst-case response-time for messages in the bluetooth. We are using frequency hopping mechanism in order to retrieve the useful distribution of pockets instead of the worst-case scenario in bluetooth communication. Since the bluetooth systems are not synchronized, the number of bluetooth hops which it overlaps will depend not just on the 802.11 packet's length but also on the time offset between the packet and the hops. The best option to avoid the overlap problem is the time period. This analysis was concerned only with the timing relationships between an 802.11 packet and the bluetooth hops.

Abstract


The response time is one of the main constraints in bluetooth synchronization and message transfer. This paper provides a novel approach for calculating a probabilistic worst-case response-time for messages in the bluetooth. We are using frequency hopping mechanism in order to retrieve the useful distribution of pockets instead of the worst-case scenario in bluetooth communication. Since the bluetooth systems are not synchronized, the number of bluetooth hops which it overlaps will depend not just on the 802.11 packet's length but also on the time offset between the packet and the hops. The best option to avoid the overlap problem is the time period. This analysis was concerned only with the timing relationships between an 802.11 packet and the bluetooth hops.
