This paper proposed distributed strategies for the joint control of power and data rates in a wireless sensor network.By adapting a linear state-space model to describe the network dynamics,the power controller with static output feedback is designed in the case that the transmission signal are not always available and the estimation of the unmeasured states constitutes a crucial task in the network.The existence of the power controller is formulated as the feasibility of the convex optimization problem,which can be solved via a linear matrix inequality (LMI) approach.The proposed algorithm also caters to the uncertainties in the network dynamics.Numerical examples are given to illustrate the effectiveness of the proposed methods.
