Building a Communication Bridge with Mobile Hubs
We study scenarios where mobile hubs are charged with building a communication bridge between two given points s and t. We introduce a new bi-criteria optimization problem where th...

Lifetime maximization for amplify-and-forward cooperative networks
Power allocation strategies are devised to maximize the network lifetime of amplify-and-forward (AF) cooperative networks in this work. We consider the scenario where one source an...

Assigning Sensors to Missions with Demands
We introduce Semi-Matching with Demands (SMD), which models a certain problem in sensor networks of assigning individual sensors to sensing tasks. If there are multiple sensing tas...
