Abstract
The growing popularity of multimedia technology has attracted designers to devise new technologies in cellular systems in order to increase their capacity as well as to improve the network performance. We study the multihop medium access control (mMAC) scheme, which was proposed by Li and Chong and could significantly improve the system performance over CDMA/PRMA for SCNs. However, it’s noticed that the mMAC protocol does not provide satisfying performance when the cell radius is large and relays are unnecessarily involved especially because all mobile stations (MSs) in the outer region adopt two-hop transmissions. In this paper, we propose two new medium access control (MAC) protocols, multi-medium MAC with Retransmission (mmMAC/RT) and opportunistic MAC (OMAC), to improve the performance of uplink voice transmissions for TDD-CDMA multihop cellular networks.
