Virtual Localization for Robust Geographic Routing in Wireless Sensor Networks
Geographic routing protocols are well suited to wireless sensor networks because of their modest resource requirements. A major limiting factor in their implementation is the requirement of location information. The virtual localization algorithm provides the functionality of geographic routing without any knowledge of node locations by constructing a virtual coordinate system. It differs from similar algorithms by improving efficiency – greedy routing performs significantly better over virtual locations than over physical locations. The algorithm was tested and evaluated in a real network environment.
OBJECTIVE. The purpose of this study is to evaluate the diagnostic value of in vivo MR spectroscopy (MRS) with semilocalization by adiabatic selective refocusing (semi-LASER MRS) in differentiating...
