Abstract—WiMAX with femto cells is a cost-effective nextgeneration broadband wireless communication system. Cognitive Radio (CR) has recently emerged as a promising technology to...
Abstract— Ubiquitous computing refers to making many computing devices available throughout the physical environment, while making them effectively invisible to the user. To furt...
In this paper, we introduce and evaluate CrossTrace, a framework for performing cross-layer measurements in IEEE 802.11 based wireless networks. CrossTrace allows tracing of parame...
We propose extending these middleware approaches with suitable abstractions to better support protocolbased interaction in mobile applications. To test our approach, we created Obj...
Rate adaptation is a mechanism unspecified by the 802.11 standards, yet critical to the system performance by exploiting the multi-rate capability at the physical layer. In this ...
