ABSTRACT A cross‐layer joint optimization approach is proposed for multihop routing in time‐division duplex code‐division multiple‐access wireless mesh networks. Two timeslot scheduling schemes are investigated for time‐division duplex operations. The routing at the network layer, the packet delay at the medium access control layer, and the signal‐to‐interference‐plus‐noise ratio at the physical layer are jointly optimized in a cross‐layer manner. The results show that the proposed cross‐layer optimization algorithm significantly outperforms the shortest‐path routing algorithm with respect to overall network performance. The maximum throughput of the whole mesh network can be optimized by jointly taking into account the end‐to‐end delay and successful packet rate. Copyright © 2011 John Wiley & Sons, Ltd.
