One embodiment of the present invention provides a system for facilitating proportionally fair-share time slot reservations with a fast increase, slow decrease rate controller in an ad hoc dynamic wireless broadcast network. During operation, the system determines local time slot demand, based on transmitted and queued data corresponding to one or more previous decision points. Next, the system broadcasts the local time slot demand to one or more neighbors. The system also determines neighbor time slot demands, where a respective neighbor time slot demand indicates a particular neighbor's local time slot demand corresponding to one or more previous decision points. Next, the system determines neighborhood time slot demand, based on the local time slot demand and the neighbor time slot demands. Next, the system determines allowable reserved time slots based on the local time slot demand and allowable reserved time slots corresponding to one or more previous decision points.
