Scheduling and Dynamic Relocation for IEEE 802.11s Mesh Deterministic Access

Deployment of Wireless Mesh Networks (WMNs) is becoming increasingly popular due to the low-impact and lowcost features of wireless devices. This is especially true for WMNs based on IEEE 802.11 which, however, does not include native support for multi-hop relaying. This gap is being filled by the Task Group 's' of the IEEE 802.11 which has recently published an amendment in order to add mesh functions to the popular standard IEEE 802.11. Among the enhancements proposed, Mesh Deterministic Access (MDA) allows mesh routers to negotiate periodic collision-free transmission opportunities, called MDAOPs, to the Medium Access Control (MAC) layer on a hop-by-hop manner. Control messages are exchanged to advertise the reserved MDAOPs in the two-hop neighborhood.
