N2 - Transmission through short-range and short-term connected Pocket Switched Networks (PSN) would become more and more popular. In this paper, we study how a mobile wireless device achieves anonymous broadcasting in PSN. We split an original message into many segments and broadcast them at different times. These segments will be received, saved in buffer and forwarded by other devices with time delay. As the time difference of arrival of these segments of a message is caused by delayed transmission and users' movements, not by the difference of geography distance, the adversary server is not able to utilize TDOA algorithm to localize the originator's real location. In the way, the originator hides its identity and location.
