Abstract
Media Access Control (MAC) must be carefully
considered in multi-hop Underwater Acoustic Sensor Networks
(UASNs) due to limited bandwidth and large propagation
delay. In particular, variable propagation delays in UASNs
cause inaccurate time synchronization and therefore make
reservation-based protocols less favorable. Large propagation
delays limit the performance of carrier sense in predicting the
status of the intended recipients, and therefore CSMA
protocols show bad performance in UASNs too. Therefore,
simple protocols, such as Aloha, show promise for UASNs. In
this paper we consider the performance of a multi-hop ppersistent
ALOHA protocol.
