We present Pool-Based APROB Channel, based on pool mix model, to provide anonymity against global active adversary. The adversary has capability to monitor all external activities of system, to delay and to create messages in the system. Our proposal is to solve the limitation of APROB Channel which concerns only global delaying adversary. Pool-Based APROB Channel provides flexibility for users to justify their level of anonymity (and speed) and satisfies probabilistic real-time condition which ensures to deliver any message within a predefined duration with high probability. Experimental evaluation shows that our system provides lower source-hiding property than APROB Channel with the same environment and users' behaviors (rate and number of sent messages).
