Distributed Diagnosis Under Bounded-Delay Communication of Immediately Forwarded Local Observations
In this paper, we study distributed failure diagnosis under k-bounded communication delay, where each local site transmits its observations to other sites immediately after each o...

Localization: Approximation and Performance Bounds to Minimize Travel Distance
Abstract—Localization, which is the determination of one’s location in a known terrain, is a fundamental task for autonomous robots. This paper presents several new basic theor...

Clock Synchronization with Bounded Global and Local Skew
We present a distributed clock synchronization algorithm that guarantees an exponentially improved bound of O(log D) on the clock skew between neighboring nodes in any graph G of ...

Depth-First Branch-and-Bound versus Local Search: A Case Study
Depth-first branch-and-bound (DFBnB) is a complete algorithm that is typically used to find optimal solutions of difficult combinatorial optimization problems. It can also be adap...

Improved Bounds for Wireless Localization
We consider a novel class of art gallery problems inspired by wireless localization. Given a simple polygon P, place and orient guards each of which broadcasts a unique key within ...
