Abstract :
Threshold access sharing (TAS) is a policy based call admission control (CAC) scheme in wireless IP networks. It has been shown to adapt well to the limited wireless resources. However, its handling of handoff calls is missing. In this paper, we proposed a hybrid scheme which combines an improved TAS scheme with a simplified rate-based borrowing scheme, aiming to improve its performance both on new call blocking and handoff call dropping probability. Our analysis and simulation have shown that the new scheme has met the expectation and its complexity is comparable to TAS.
