ABSTRACT
We design and implement global and local CAC al-
gorithms for CDMA networks, and compare their net-
work throughput for various mobility scenarios. The global
CAC algorithm is inherently optimized and uses global
information in making every call admission decision; it
yields the best possible performance but has an intensive
computational complexity. The design of the local CAC
algorithm uses global information but its implementation
in each cell uses only local information; it only requires
the number of calls currently active in that cell and thus
is very simple to implement. We show that our optimized
local CAC algorithm achieves almost the same performance
