CODA: congestion detection and avoidance in sensor networks
Event-driven sensor networks operate under an idle or light load and then suddenly become active in response to a detected or monitored event. The transport of event impulses is l...

Linear Capacity Scaling in Wireless Networks: Beyond Physical Limits?
We investigate the role of cooperation in wireless networks subject to a spatial degrees of freedom limitation. To address the worst case scenario, we consider a free-space lineof-...
