RPCP-MAC: Receiver preambling with channel polling MAC protocol for underwater wireless sensor networks - 2020

Research Area:  Wireless Sensor Networks

Abstract:

To design a reliable and energy efficient medium access control (MAC) protocol for underwater wireless sensor networks (UWSNs) is an active research area due to its variety of applications. There are many issues associated with underwater acoustic channels including long and variable propagation delay, attenuation, and limited bandwidth which pose significant challenges in the design of MAC protocol. The available sender-initiated asynchronous preamble-based MAC protocols for UWSNs are not reliable and energy-efficient. This is due to the problems caused by transmission of preambles for longer duration and collision of preambles from hidden nodes in sender-initiated preamble-based MAC protocols. To resolve these issues, the paper proposed an asynchronous receiver-initiated preamble-based MAC protocol named Receiver Preambling with Channel Polling MAC (RPCP-MAC) protocol for shallow underwater monitoring applications with high data rates. The protocol is proposed to resolve data packet collision and support reliability in an energy-efficient way without using any transmission schedule. The proposed protocol is based on the following mechanisms. Firstly, receiver preambling mechanism is adopted to reduce idle listening. Secondly, channel polling mechanism is used to determine missing data frame during its sleeping period and to minimize the active time of node and reduces energy wastage. Finally, a back-off mechanism is applied to resolve collision when preambles are received simultaneously. In addition, performance analysis through Markov chain together with its validation with simulation-based studies is reported in the paper. Both the analytical and simulation results have demonstrated the reliability achievable with RPCP-MAC while providing good energy efficiency.
