EMDA is based on a per-node reservation

of a block of contiguous transmission opportunities that are

properly dimensioned. Moreover, we further improve the neardeterministic

access of EMDA by using short jamming periods

just before these reservations. Extensive simulation results show

that our proposed MAC enlarges the voice capacity and uniformly

distribute it over the WMN. It also provide a better

performance in guaranteeing hard delay constraints, lower jitter

and lower packet losses compared to other MAC
