Constrained optimization problems that couple different cooperating users sharing the same communication network are often referred to as multiuser optimization programs. We are interested in convex discrete-time time-varying multiuser optimization, where the problem to be solved changes at each time step. We study a distributed algorithm to generate a sequence of approximate optimizers of these problems...
A framework to track the position and orientation of a moving rigid body is proposed. We consider a setup in which a few wireless sensors are mounted on a rigid body. The topology of how these sensors are mounted on the rigid body is known; however, the absolute position of the sensors or the rigid body itself is unknown. Using range-only measurements between the sensors and a few anchors (nodes with...
We consider a robotic network composed of mobile robots capable of communicating with each other. We study the problem of collectively tracking a number of moving targets while maintaining a certain level of connectivity among the robots, by moving them into appropriate positions. The distances of the robots to each other and to the targets are used to define a communication and target tracking graph,...
