The RAMA (resource auction multiple access) protocol and its variations use a collision resolution protocol based on subscriber IDs to allocate available communication resources. However, these protocols suffer from unfairness or high packet dropping probability. The authors propose and analyse a novel deterministic packet access protocol, Q-RAMA, to improve the quality of service in PCS networks. Simulation results show that Q-RAMA has the lowest packet dropping probability and better overall performance.
