Abstract
Underwater Sensor Networks (UWSN) utilise acoustic
waves with comparatively lower loss and longer range in
underwater environment than electromagnetic waves. However,
energy remains a challenging issue in addition to long latency,
high bit error rate, and limited bandwidth. Thus, collision
and retransmission should be efficiently handled at MAC layer
in order to reduce the energy cost and also to improve the
throughput and fairness across the network. In this paper,
we therefore propose a new reservation-based distributed MAC
protocol, which employs a duty cycle mechanism to address the
spatial-temporal uncertainty and the hidden node problem to
effectively reduce collisions and retransmissions. Our extensive
simulation study reveals that our proposed protocol can efficiently
handle the traffic contention to achieve significant improvement
in terms of energy consumption, throughput, and fairness.
