Conclusion
We have reviewed the 802.16 mesh protocol. This protocol uses TDMA to pro- vide QoS in the mesh backbone. QoS is available in the MAC layer, so we have introduced a subnetting scheme in the network layer that takes advantage of the QoS. The subnetting allows us to move all QoS decisions to the edge of the network. We have also proposed a CS that glues together the subnetting in the network layer to different classes of service available in 802.16 mesh networks. IEEE 802.16 provides for hop-by-hop encryption of data traffic; how- ever, this may be costly to implement in practice. We have proposed an end-to-end security scheme that takes encryption away from the mesh back- bone to the clients using the network. This should significantly simplify the
implementation of mesh routers.
