We study the energy consumption of individual links in wireless sensor networks (WSN). Three widely used digital modulation schemes, i.e. MQAM, MPSK, and MFSK, are analyzed and com...
This paper presents a new methodology for system-level power and performance analysis of wireless multimedia systems. More precisely, we introduce an analytical approach based on ...

In this paper, we propose an "in-network" diversity combining scheme for image transport over wireless sensor networks. We consider a wireless sensor network with both w...
Abstract-- We identify an analytical expression for the distortion of a scalable video bitstream containing a Base Layer (BL) and one or more Enhancement Layer (EL) bitstreams. Con...
— Providing delay guarantees to time-sensitive traffic in future wireless multimedia networks is a challenging issue. This is due to the time-varying link capacities and the vari...
