- The novelty of this work is to employ the graph colouring technique to propose a distributed MAC protocol for acoustic UWSNs. To support spatial reuse, any concurrent conflict-free transmissions should be allowed among all two-hop clusters. This is achieved by developing a distributed clustering approach for up to two-hop neighbouring sensors and then to address the hidden and expose node problems by removing any colour conflict in two-hop neighbouring graph. We are then able to assign a unique colour, i.e. time-slot, to every node in the network in a distributed manner. Nodes with the same colour can thus transmit concurrently.
