Abstract:
This paper carried out a study on the bandwidth request for real-time polling
services. In our study, we discovered that although the base station granted the subscriber
station to send the bandwidth request, the subscriber station may not be able to allocate
the bandwidth request. It is due to processing delay and multicast polling in the subscriber
station, which results the bandwidth request being padded unintentionally. The loss of
bandwidth requests will cause the degradation of the real-time polling service
performance. Therefore, we propose a scheme to overcome this problem. The results of
the experiment show that the proposed scheme improves the performance of real-time
polling services.
