Approximating Minimum-Power k-Connectivity
Abstract. The Minimum-Power k-Connected Subgraph (MPkCS) problem seeks a power (range) assignment to the nodes of a given wireless network such that the resulting communication (su...

Jamming sensor networks: attack and defense strategies
Wireless sensor networks are built upon a shared medium that makes it easy for adversaries to conduct radio interference, or jamming, attacks that effectively cause a denial of se...

Rate and power allocation under the pairwise distributed source coding constraint
We explore the problem of rate and power allocation for a sensor network where pairwise distributed source coding is employed (introduced by Roumy and Gesbert `07). For noiseless n...
