Temperature- and SNR-based On Demand Routing Protocol for Underwater Communication

Underwater Communication comes with various obstacles which involves the interaction between acoustic signals and the physical features of the medium which include pH value, salinity and temperature. This paper focuses on surveying and proposing routing algorithms which takes into consideration of the temperature and well as the various factors that affect it within the medium. The paper proposes a new routing algorithm which will decide the next hop to be chosen based on the best Signal to Noise Ratio (SNR) value of its neighbours and it's study based on the effect temperature has on it. A model to calculate temperature has been developed. The SNR value being calculated considers physical parameters of the medium including pH, salinity and temperature. The routing algorithm is mathematically modelled and then simulated in UnetStack 3 for proof of correctness.
