Multiple Access Scheme with Priority for Active Safety Transportations

Abstract

Abstract—We propose a new multiple access technique serving multiple groups of useres with different priorities. The proposed system is consisting of: (a) top emergency, (b) emergency, and (c) normal groups. We give priority based on different accessible time-slot to each group. We expect that the results are useful for further development in future wireless massive communication systems.
