Consensus protocols have gained a lot of interest in the recent years. In this thesis, we study optimization, control, and game theoretical problems arising in consensus protocols. First, we study optimization techniques for weight selection problems to increase the speed of convergence of discrete-time consensus protocols on networks. We propose to select the weights by applying an approximation algorithm: minimizing the Schatten p-norm of the weight matrix. We characterize the approximation error and we show that the proposed algorithm has the advantage that it can be solved in a totally distributed way. Then we propose a game theoretical framework for an adversary that can add noise to the weights used by averaging protocols to drive the...
