Résumé / Abstract

This paper proposes a new multiple access control protocol, the hierarchy schedule sensing (HSS) protocol, for CDMA wireless data networking with high terminal density in a relatively small area, a typical example of which is a data-centric device network based on Bluetooth technology to provide device-to-device wireless connections. This paper studies the packet collision effect on network performance under the (HSS) protocol, in which a common-coded permission frame (PF) beacon is employed to schedule request transmissions to avoid packet collisions. To reduce the scheduling delay, hierarchical group-based codes are adopted in the scheme. The performance of such a network is evaluated by a Markov chain model. The average packet collision rate with capture effect is derived explicitly. The performance of the proposed protocol is compared with the triple-receiver-based code (triple-R) protocol, which does not use the PF beacon to regulate request packet transmissions. It is revealed from the obtained results in this paper that, despite of its low implementation complexity, the HSS protocol is a fairly robust multiple access control protocol featured by uniformly high throughput, low delay and stable performance, even under a relatively heavy offered traffic load.
