Abstract : The XTC ad-choc network topology control algorithm shows three main advantages over previously proposed algorithms.

First, it is extremely simple. Second, it does not assume the network graph to be a Unit Disk Graph; XTC proves correct also on general weighted network graphs.

Third, the algorithm does not require availability of node position information. Instead, XTC operates with a general notion of order over the neighbors’ link qualities.

In the special case of the network graph being a Unit Disk Graph, the resulting topology proves to have bounded degree, to be a planar graph, and—on average-case graphs—to be a good spanner. Employed on Euclidean and Unit Disk Graphs.
