Investigation of Timescales for Channel, Rate, and Power Control in a Metropolitan Wireless Mesh Testbed

We investigate the timescales for channel assignment, power control, and rate control in a metropolitan mesh network with links whose distances range from 1.6 to 5 Km. In particular, for channel assignment we consider a procedure that accounts for both intra-network and external interference, and investigate the timescale at which channels need to be re-assigned in order to achieve high performance. For rate control, we compare an auto-rate algorithm that adapts the transmission rate on a per-packet basis, with a fixed transmission rate scheme. For power control, we investigate the minimum transmission power required to achieve a high throughput, and how this power changes during the course of a day.
