Designed and developed a simulator in C for performance investigation (especially for the study of routing algorithms) for opportunistic networks (a.k.a. delay-tolerant networks).

Studied the principle and infrastructure of the telecommunication system, analyzed the demand for the potential service from the customers' perspective and proposed several value-added service, and finally was involved in the system maintenance and improvement.
