The RAMA (resource auction multiple access) protocol uses a scheme where the access procedure is divided into fixed length cycles. A variation of RAMA, the tree-search resource auction multiple access (TRAMA) protocol, was proposed to reduce the length cycle. Both protocols present disadvantages, although different ones. The authors propose and evaluate another variation of RAMA, fair resource assignment multiple access (F-RAMA). Simulation methods were used to calculate packet dropping probability, access delay and statistics of speech clipping in voice transmission.
