Title: Compressive Sensing for Wireless Localization

 

Abstract: I will briefly introduce how compressive sensing can be exploited in wireless localization applications. The talk contains basically four parts: 1) Compressive sensing based MDS localization 2) Compressive sensing based RSS-based indoor localization; 3) Compressive sensing based multi-target localization; 4) Our recent results

 

Title: Computing Wireless Capacity

Abstract: In this paper we address two common questions in wireless communication from an algorithmic perspective, assuming a geometric path loss model: First, how long does it take to satisfy an arbitrary set of wireless communication requests? Second, given a set of arbitrary communication requests, how many of them can be transmitted concurrently. Our main results are efficient algorithms that find a constant approximation for the second problem, and a logarithmic approximation for the first problem. In addition we present a robustness result, showing that constant parameter and model changes will modify a result only by a constant.
