Delay in Underwater Acoustic CSMA Networks

The paper considers the delay performance of an underwater acoustic multiple access network where bottom mounted sensor nodes transmit packets to an aggregation point. The focus is on Carrier Sense Multiple Access (CSMA) slotted Aloha. It is assumed that packets generated by the sensor nodes can be described by independent Poisson processes. The delay is investigated under the assumption that there is a pseudo-Bayesian stabilization of the considered CSMA network. Numerical examples are presented that illustrate the delay performance.
