چکیده

There are considerable serious propagation delay rate and high error rate in case of data transmission in the poor and causal environment, such as underwater. Like this environment usually has heavy fluctuation of error rate and limited wireless communication state. Therefore, mechanism using in such environment has to be efficient and simple. This paper suggests a novel block ack mechanism, called the Pervasive Block ACK (PBA), which transmits aggregated ACKs. This mechanism takes effect on reducing the amount of traffic, decreasing overhead and delay rate in poor environment networks like underwater. Additionally, we are able to look forward to reducing the energy consumption of whole network. We can find the proposed PBA is more efficient than other methods, such as BA and ARQ through analyzing numerical result based analytical formula in this paper. Key-Words: UW-ASN (Underwater Wireless Acoustic Sensor Network), PBA (Pervasive Block Ack), Block Ack, ARQ
