Abstract
We present S-XTC, a topology control algorithm that uses the received signal strength indicator (RSSI) of the radio on the sensor nodes. The algorithm is based on XTC, an simple topology control algorithm that constructs a relative neighborhood graph. In contrast to XTC our extended Version is robust against an error-prone RSSI. It guarantees the connectivity and a bounded degree and is able to adapt to Network changes. We discuss the shortcomings of previous algorithms and evaluate S-XTC by analytical proofs, simulation results and a case study. We have successfully implemented and tested S-XTC on the BTnodes.
