RID: radio interference detection in wireless sensor networks
— In wireless sensor networks, many protocols assume that if node A is able to interfere with node B’s packet reception, then node B is within node A’s communication range. I...

Fast Distributed Algorithm for Convergecast in Ad Hoc Geometric Radio Networks
—Wireless ad hoc radio networks have gained a lot of attention in recent years. We consider geometric networks, where nodes are located in a euclidean plane. We assume that each ...
