On Asymmetric Distributed Source Coding For Wireless Sensor Networks
(2011-01-19)
We are concerned with addressing the worst-case distributed source coding (DSC) problem in asymmetric and interactive communication scenarios and its application to data-gathering wireless sensor networks in enhancing their ...
Formal Verification Of Analog And Mixed Signal Designs Using Simulation Traces
(2011-07-08)
The conventional approach to validate the analog and mixed signal designs utilizes extensive SPICE-level simulations. The main challenge in this approach is to know when all important corner cases have been simulated. An ...
Distributed Wireless Networks : Link Scheduling And Application Delay Modelling
(2013-05-23)
We address several problems that arise in a multihop wireless mesh network. First, we study the problem of joint congestion control, routing and MAC layer scheduling. We formulate the problem as an aggregate utility ...
