Speaker: Shreeshankar Bodas, MIT Abstract - We look at the problem of designing "efficient" resource allocation algorithms for wireless networks. The volume of data transferred over the wireless network has been ever-growing, but the resources (time, frequency) are not growing at the same rate. We therefore need to design good resource allocation schemes to guarantee a good quality of service to the users.
In the first part of the talk, we look at the wireless access network, such as Wi-Fi. We have three objectives: ensure high resource utilization, low user-perceived latency, while keeping the computational burden on the devices to a minimum. An interesting recent result by Shah et al says that these three objectives are incompatible with other, unless P=NP. We design a physical layer-aware medium access algorithm that simultaneously achieves the three objectives, and thereby show that the hardness result by Shah et al is an artifact of a simplistic view of the physical layer.
The second part of the talk focuses on designing scheduling algorithms for wireless downlink networks, such as a cellular network. Our objectives (again) are high resource utilization, low per-user delay, and a "simple" algorithm. We outline the drawbacks of the classic MaxWeight-type algorithms, and design iterative resource allocation schemes that perform well on all the three fronts.

MERL Host: Anthony Vetro Abstract - Today, photodynamic diagnostics is commonly used for cancer detection in endoscopic interventions of the urinary bladder. Although the visual contrast between benign and malignant tissue is significantly enhanced using fluorescence markers, the field of view (FOV) of the endoscope becomes very limited. This impedes the navigation and the re-identifying of multi-focal tumors for the physician. Thus, new image mosaicking algorithms and visualization methods, which provide larger FOVs in real-time from free-hand bladder scans are developed and will be presented. Furthermore a novel method for an automatic control of seamless inspections using graphs are addressed. Going beyond image processing, a first low-cost inertial 3-D navigation system will be introduced, and a guided navigation tool for tumor re-identification and its application to virtual endoscopy will be discussed.
