A novel Medium Access Control (MAC) protocol, named Dynamic Resource Assignment Multiple Access enhanced version (DRAMA+), is proposed in this paper for Low Earth Orbit - Mobile Satellite Systems (LEO-MSSs). It is based on a Time Division Multiple Access air interface and utilizes access slots distinct from information slots. The DRAMA+ scheme realizes an efficient access phase and manages transmission requests with an on board scheduler. On the basis of suitable models for both isochronous voice sources with activity detection and data bursty sources, we have shown that DRAMA+ outperforms other protocols in the literature.

Abstract
A novel Medium Access Control (MAC) protocol, named Dynamic Resource Assignment Multiple Access enhanced version (DRAMA+), is proposed in this paper for Low Earth Orbit - Mobile Satellite Systems (LEO-MSSs). It is based on a Time Division Multiple Access air interface and utilizes access slots distinct from information slots. The DRAMA+ scheme realizes an efficient access phase and manages transmission requests with an on board scheduler. On the basis of suitable models for both isochronous voice sources with activity detection and data bursty sources, we have shown that DRAMA+ outperforms other protocols in the literature.
