Mitigation of the Propagation of Localization Error Using Multi-Hop Bounding
Abstract—In ad hoc position-location networks, location information is obtained through the sequential estimation of node locations. An unlocalized node can estimate its location...

Protocols and Lower Bounds for Failure Localization in the Internet
Abstract. A secure failure-localization path-quality-monitoring (FLPQM) protocols allows a sender to localize faulty links on a single path through a network to a receiver, even wh...

Primal-dual meets local search: approximating MST's with nonuniform degree bounds
We present a new bicriteria approximation algorithm for the degree-bounded minimum-cost spanning tree problem: Given an undirected graph with nonnegative edge weights and degree b...

Lower bounds on locality sensitive hashing
Given a metric space (X, dX), c ≥ 1, r > 0, and p, q ∈ [0, 1], a distribution over mappings H : X → N is called a (r, cr, p, q)-sensitive hash family if any two points in...
