Performance evaluation of two classes of packet access for cellular radio
John A. Dunlop, Y. Kriaras, Jamil Yusuf Khan, Sinead Gormley · 1991
The suitability of packet transmission on the air interface of a cellular system is examined. Packet transmission promises to provide the flexibility required to accommodate new services and technologies with variable bit-rate requirements by allocating bandwidth on demand. An investigation is presented into the performance of two classes of packet access: time multiplex base control multiple access with collision detection (TM-BCMA/CD), which is a slotted random access technique, and packet reservation multiple access (PRMA), which is a reservation based access technique. The performance of PRMA and TM-BCMA/CD is compared with an equivalent fixed-allocation TDMA system. >
