No-Collision Scheduling Methods for Real-Time Transmission

Focusing on the subproblem ( 3.2 ) in the proposed dynamic resource regulation framework, this chapter introduces collision-free real-time scheduling algorithms to allocate resources in IWNs so that real-time transmissions are performance controllable. In Sect. 5.1, we present the background of this chapter. In Sect. 5.2, based on an inter-network collision model, we propose algorithms to optimize channel requirements and allocate different channels to multiple networks. These algorithms can isolate coexisting networks and eliminate inter-network collisions. In Sect. 5.3, for each isolated network, the time-triggered data and the event-triggered data are jointly scheduled. Our algorithm allocates different resources to time-triggered data and evet-triggered data, and generates fine-grained schedules for each data packet. In this way, we can improve the real-time performance of the time-triggered data and schedule the event-triggered data at any time.
