An analytical model for the directional hybrid MAC protocol in the IEEE 802.15.3c

Abstract

Nowadays, mobile data demand has grown significantly. Millimeter-wave (mm-wave) bands are a favorable technology to support high data rate communication. The IEEE 802.15.3c standard is an attractive candidate for mm-wave carrier frequencies for short-range indoor applications. Providing a comprehensive analytical model of the medium access control (MAC) layer gives great information to improve network performance. In this paper, for the first time, a comprehensive Markov chain model has been presented for the IEEE 802.15.3c standard by considering the directional antenna , hybrid MAC and queue. The exact queue models ( M / G /1 and M / D /1 queue) have been considered for the Regular Contention Access Period (RCAP) and Channel Time Allocation Period (CTAP) areas. The number of beam sectors and path loss model for the directional antenna is considered in the presented model. The most essential analytical parameters including throughput, delay, reliability, queue size, and system instability of each RCAP and CTAP area for the different number of sectors, RCAP area length, nodes, traffic and room size, have been investigated. Maximum throughput has been determined for the optimum value of these parameters. OPNET simulation validates our represented analytical model and shows that it is more accurate than other states of the art articles.
