Abstract :
Several channel de-allocation schemes in GSM/GPRS networks are proposed, such as DA_RANDOM, DA_RICHEST, DA_POOREST, DA_OLDEST, DA_YOUNGEST, and schemes where channel de-allocation is on demand are studied. DoD (de-allocate on demand) was originally proposed for wireless local loop networks; we expand this work to accommodate GSM/GPRS networks, and de-allocation schemes with DoD or with AD (always de-allocate) are studied. Our study quantitatively indicates that DoD may outperform channel de-allocation schemes with AD or ND (no de-allocation), and for de-allocation schemes with DoD, random de-allocation on demand (DoD_R) is better than other schemes.
