Renewable Energy Powered, Disaster-Resilient Wireless Network Infrastructure

Because of rapid increase of smart phones, mobile phone operators are desperately trying to offload mobile phone traffic to femto cells, WiFi hotspots or WiMAX coverage. On the other hand in Japan, because many base stations stopped operation due to long commercial power failure or broken fiber trunk after Great East Japan Earthquake, people began thinking resilience of network infrastructure seriously. Attaching large batteries or powering mobile phone base station by renewable energy, however, is not usually practical because of the size and weight of the equipments. In this talk, we investigate about the feasibility of WiFi-based wireless network infrastructure powered by renewable energy, which is connected by fiber trunk and is used to offload mobile phone traffic in ordinary times and act as a wireless-relayed mesh network after disaster.

The Positioning of Non-Volatile Memory in Embedded System Designs

In recent years, non-volatile memory has shown its great potentials in serving as a layer in the memory hierarchy, such as flash memory for the secondary storage of mobile devices. Their inherent characteristics also point out new directions in system designs and grand challenges. In this talk, we will first have a brief introduction to the non-volatile memory, especially flash memory and phase change memory. We will then present challenges and solutions for flash memory as a storage medium. The talk is concluded by key challenges for system designs of phase change memory.
