The rapid development of society has generated an increasing number of human activities that have gradually modified the marine environment. Wirless sensor networks present a potentially promising alternative for monitoring marine environments. Usually, the topology of a monitoring system is integrated by a group of fixed buoys that gather data, and a coordinator node is responsible to sent the data to a processing center. This topology does not demand a routing protocol, however in some situations such as monitoring currents behavior demands a certain level of bouys mobility and as a consequence requieres a more complex communication mechanism to send the information to the processing center. This paper presents HYRMA, a clusterbased hybrid routing protocol focused on the reduction of energy consumption which is applied in a marine environment Based on the results obtained from simulator, HYRMA is shown to be a suitable mechanism for data transmissions in a WSN applied in a marine environment.
