Wireless technology has been changing our lives and businesses over the past decades. So far, a variety of different wireless networks, such as WiFi and Cellular Networks, have been widely deployed. Localization and security are two important research areas in wireless networks. In this presentation, a distributed localization scheme for mobile wireless networks, MALL, is first discussed. Technically, MALL employs a matrix-completion approach to utilizing the collected connectivity and distance information, which leads to high-precision localization. In addition, since MALL only involves convex optimization and low-complexity non-convex optimization, it can localize mobile nodes at a fast pace. In the second half of the presentation, a light-weight authentication scheme for end-to-end security in mobile clouds, MDLA, is included. Specifically, both the up-to-date time and location of mobile cloud clients are used in MDLA to enable the effective and low-complexity authentication algorithm.
