Li Young Researcher Award of ACM in 2003 Distinguished Research Award from National Science Council in Taiwan in 2006 Author (cont’d) His research interests include routing protocols channel assignment mechanisms performance modeling in wireless mesh networks Overview Abstract Introduction Challenges Need for a New Routing Metric Load Distribution among Channels Dependence on Channel Assignment Cross-Layer Design of Routing and MAC Routing Metrics WCETT NBLC Performance Comparison Open Research Issues QoS Routing Multipath Routing Multicast Routing Conclusion Abstract Abstract Employing multiple channels the problem of capacity degradation in multihop wireless networks. Existing routing schemes inefficient routing paths in multichannel WMNs. To fully exploit the capacity gain the availability of multiple channels distribute traffic load We highlight the challenges in designing routing algorithms examine existing routing metrics that are designed for multichannel WMNs Introduction Introduction The major challenge to conquer the degradation of capacity due to the interference problem Multiple channels is an effective approach concurrent transmissions on nonoverlapping channels The multichannel environment introduces new research challenges routing scheduling allocating wireless channels In this art
