Adaptive Coded Modulation for Stabilization of Wireless Networked Control Systems over Binary Erasure Channels

This paper proposes adaptive coded modulation for stabilization of wireless networked control systems (WNCSs). We combine a well-known data rate theorem with adaptive coded modulation to guarantee stability and optimize the spectral efficiency in WNCSs. We believe that this is the first work in adaptive coded modulation for stabilization. In addition, we propose three schemes to optimize various objectives with given constraints. Our proposed schemes are as follows: maximizing throughput with energy constraint (MaxTEC), minimizing energy with throughput constraint (MinETC), and minimizing delay with energy constraint (MinDEC). The numerical results show that each scheme is able to select the optimal modulation to optimize objectives at given channel conditions and constraints.
