GPS-Free node localization in mobile wireless sensor networks
An important problem in mobile ad-hoc wireless sensor networks is the localization of individual nodes, i.e., each node’s awareness of its position relative to the network. In t...

Near-Optimal Lower Bounds on the Multi-Party Communication Complexity of Set Disjointness
We study the communication complexity of the set disjointness problem in the general multi-party model. For t players, each holding a subset of a universe of size n, we establish ...
