A paper which is co-authored by University of Macau (UM) Rector Wei Zhao, his research team, and Prof. Li Ming from East China Normal University has been ranked among China’s 100 Most Influential International Papers (2012) and the Latest Most Influential Papers in China (on Biology), according to a recent issue of Statistical Data of Chinese S&T Papers 2013 released by the Institute of Scientific and Technical Information of China (ISTIC) under the Ministry of Science and Technology. Another paper co-authored by Rector Wei Zhao and Prof. Fu Xinwen from the University of Massachusetts received the Best Paper Award at the Eighth International Conference on Wireless Algorithms, Systems, and Applications (WASA 2013).

The first paper, entitled “Visiting Power Laws in Cyber-Physical Networking Systems”, written under the National 973 Internet of Things Project, is internationally acclaimed for its theoretical model which helps expand our knowledge of the laws of network-transmitted data and greatly facilitates the analysis of the upper reaches of peer-to-peer data latency in heterogeneous network. This paper demonstrates UM’s innovation in research and produces a significant impact on the development of the internet of things.  

According to Rector Wei Zhao, any large-scale cyber-physical system such as the internet of things is comprised of numerous sub-systems. These sub-systems in turn have their own structures and network protocols which are hard to be compatible with one another, and such an incompatibility is restricting the development of the internet of things. However, the need for real-time communication and system control requires close association of these sub-systems. Hence a uniformed network data model is of vital importance to the effective allocation and management of network resources; or else any large-scale data network would be made ineffective and weak. One of the challenges facing the development of the internet of things is building a uniformed and effective network model. Scientists have observed that the distribution of network data very often works in the same way as that under the power-law, but they have yet to formulate an underpinning theoretical model for that. This award-winning paper reveals for the first time that such a phenomenon is a result of a massive amount of data distributed statistically in conformity with the special fractional partial differential equations.   

The other paper, entitled “Effective RSS Sampling for Forensic Wireless Localization”, which is co-authored by Rector Wei Zhao and Prof. Fu Xinwen, a former student of his and currently an associate professor at the University of Massachusetts, proposes a ground-breaking theory of signal control at a certain point by means of a particular pattern of sampling. The Nyquist theory is then used to apply to the result of the sampling to restore the original pattern of signal emissions so that interferences can be avoided. By applying the restored signal to compute the position, the problem of positioning is solved. This method does not rely on any system of signal feedback other than an RSS receiver. Empirical studies have shown that by using this method, positioning is by far more precise than using other techniques. The wireless positioning advocated in the paper has wide applications and very useful for wireless positioning in the complex indoor situations.

One of the most important conferences on wireless network, the WASA focusses on the most advanced technologies of wireless network in the aspects of algorithms system, security and application. The conference proceedings are published in the international refereed journal Lecture Notes in Computer Science (LNCS). The ISTIC is the most authoritative rating body in China on the quality and influence of the technology research papers. It draws its data and statistics from various influential databases including the Science Citation Index (SCI), the Engineering Index (EI), the Conference Proceedings Citation Index – Science (CPCI-S), MEDLINE, the Social Sciences Citation Index (SSCI), and Scopus. When selecting the 100 most influential international papers in China, apart from using the authoritative indexes as a guide, the ISTIC also convened a special panel of experts to rate the papers in terms of whether the research is groundbreaking, whether the journal that carries the paper is of good academic standing, and whether the study is at the frontier in its field. It also considered the type of the study and the references used. Thus, the winning of these awards really testifies to UM’s research strength.
