Wireless multi-hop architectures are increasingly used in many wireless networks. However, it is very difficult to analyse and guarantee end-to-end delay performance over multi-hop wireless paths. In this paper, we develop a cross-layer analytical model to characterise the multi-hop delay performance and derive new mathematical formulae of (DBVP), delay mean and jitter of end-to-end communications...
Wireless mesh networks (WMNs) have been proposed to provide rapid deployment and easy reconfiguration of wireless broadband communications. WMNs can interoperate with WiMAX, Wi-Fi, sensor, or cellular networks in the hybrid working environments to relay packets robustly among these heterogeneous networks and significantly extend the coverage of individual wireless access networks. Many recent studies...
In this paper, we model the location-dependent throughput and delay in wireless mesh networks. We analyze packet arrival rates and packet departure rates for the forwarding queues at relaying nodes and then derive the throughput and packet delay experienced by nodes at different hop count distances to the gateway. Based on this model, we further analyze how network design strategies affect the throughput...
In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
