A MAC Aware Cross-Layer Routing Approach for Wireless Mesh Network

摘要：

Wireless Mesh Networks (WMNs) are an emerging architecture based on multi-hop transmission. Improving the performance in face of unreliable wireless medium will support WMNs to be a very cost-effective solution for wireless ISPs. In this paper, we propose a new cross layer routing metric called expected transmission efficiency (ETE), which aims to find high throughput and low delay paths. ETE takes into account MAClayer link quality as the number of packets retransmissions on wireless link and the contention level along the paths. The implementation of ETE metric in proactive routing protocol such as Destination Sequenced Distance Vector (DSDV) is also given. Simulation results show that our proposed cross layer routing metric achieves better performance in comparison to the traditional minimum hop metric.
