摘要： [Display omitted] •We design two schemes for forwarding broadcast messages in IEEE 802.16 multi-hop relay networks.•The proposed schemes consider a connection identifier (CID) translation strategy.•We provide the analysis of the forwarding performance.•Considering CID translation will reduce the amount of resources used.•Considering CID translation will reduce the transmission latency. Although the IEEE 802.16j standard introduces a connection identifier (CID)-based forwarding scheme and a tunnel-based forwarding scheme, these schemes exhibit poor performance when forwarding broadcast messages. This study considers a CID translation strategy and proposes two CID-translated forwarding schemes for IEEE 802.16 multi-hop relay networks. The basic CID-translated forwarding scheme does not require to append the relay MAC header of the tunnel-based scheme to the broadcast messages. The enhanced CID-translated forwarding scheme further divides a broadcast message into a common part and a specific part and forwards these parts in a multicast manner and a broadcast manner, respectively. Simulation results validate that the basic CID-translated forwarding scheme uses fewer resources than the tunnel-based forwarding scheme. Moreover, the enhanced CID-translated forwarding scheme outperforms the basic CID-translated forwarding scheme in terms of the system resources used and transmission latency. 出版者： Elsevier Ltd 出版日期： 2014-02-01 出處： Computers & electrical engineering, 2014-02, Vol.40 (2), p.563-576 版權： 2013 Elsevier Ltd 識別號： ISSN: 0045-7906 識別號： EISSN: 1879-0755 識別號： DOI: 10.1016/j.compeleceng.2013.07.025
