— Previous results show that a node’s throughput scales poorly as the network size increases when every node has traffic. However, in many cases, only a fraction of nodes in l...

—We analyze the multihop delay of ad hoc cognitive radio networks, where the transmission delay of each hop consists of the propagation delay and the waiting time for the availab...

Hierarchical cooperation has recently been shown to achieve better throughput scaling than classical multihop schemes in static wireless networks. However, the end-to-end delay of ...
