Dynamic vehicle routing with heterogeneous demands
— In this paper we study a variation of the Dynamic Traveling Repairperson Problem (DTRP) in which there are two classes of demands; high priority, and low priority. In the probl...

Power Allocation in Wireless Relay Networks: A Geometric Programming-Based Approach
—1 In this paper, we consider an amplify-and-forward (AF) wireless relay system where multiple source nodes communicate with their corresponding destination nodes with the help o...

Reconstructing sparse signals from their zero crossings
Classical sampling records the signal level at pre-determined time instances, usually uniformly spaced. An alternative implicit sampling model is to record the timing of pre-deter...

Cooperative MIMO-beamforming for multiuser relay networks
In this paper, we develop a beamforming algorithm for multiuser MIMO-relaying wireless systems. We consider a relaying scenario with multiple sources transmitting to one or more d...

Network Coding for Two-Way Relaying: Rate Region, Sum Rate and Opportunistic Scheduling
—Network coding for two-way relaying in a three-node network is considered. The achievable rate regions under both traditional four-slot multi-hopping (FSMH) and network coding (...
