Institute of Network Engineering


As the first Network Engineering research and education institute in a public university in Taiwan, the institute focuses on network and communication research and education. The institute outperforms other departments and institutes in Taiwan in the fields of mobile communications, wireless networks, fiber-optic networks, and network security. The institute emphasizes the impact of research results and its faculty members have obtained many significant achievements, which surpass any other schools of computer science in the country. Many faculty members serve as editors of IEEE Transaction journals. Many faculty members have served as program committee members for prestigious international conferences and received best paper awards. Two professors have been granted Outstanding Research Awards by the National Science Council. Moreover, the institute faculty includes fellows of IEEE, ACM, AAAS, and IET.
