The uniqueness and versatility of Wireless Sensor Network (WSN) makes it an indispensable tool in monitoring almost any quantitative raw data from the environment. This paper reviews the characteristics and applicability of WSN to monitor seismic and infrasonic signals from active volcanoes. A sensor network deployment infrastructure that integrates to centralized data storage was proposed. This infrastructure was aimed to offer remote network monitoring, data management and maintenance. A simple and efficient reservation-based medium access control (MAC) protocol was developed for the proposed deployment. Using the network topology and parameters of the proposed sensor deployment, the performance of this MAC protocol was simulated in parallel with implementations similar to SMAC and TMAC. The simulation results indicated that the proposed MAC protocol performed better in terms of power usage, sleep and delay time.
