Abstract :
A hybrid protocol, W-VTCSMA, is presented which uses both virtual clocks and windows. It is shown to have better performance over a wide range of load conditions. Few protocols exist for the soft real time environment. The authors present P-VTCSMA, a protocol that transmits a tardy message using a value function driven probability distribution. It is shown how to increase the overall system value under a broad range of load conditions
