This paper introduces the problem of fault tolerant topology control for one-to-all communications in symmetric wireless networks. We investigate two algorithms to address the problem, namely Minimum Weight-Based Algorithm (MWBA) and Nearest Neighbour Augmentation Algorithm (NNAA) and prove that the former is a 4k approximation and the latter is a (k + 4) approximation. Through simulations, we evaluate the average performance of these two algorithms and find that MWBA is slightly better than NNAA in terms of the total power consumption.
