Abstract:

An admission selection algorithm utilizing delayed rejection model for heterogeneous wireless networks (AS-DRM) was proposed. The concept of buffer was introduced, elastic services were allowed to wait in the buffer until they could be serviced successively. Five-dimensional Markov queuing model was built by queuing theory for resource occupied in heterogeneous networks. The system performance was analyzed and evaluated. Simulation shows that this algorithm evidently decreases the blocking rate for elastic services, and the system performance is improved.

Key words: delayed rejection, admission selection, resource grid, heterogeneous networks
