Abstract
Traditional cable-based geophone network is not an efficient way of seismic data transmission owing to the related cost and weight. To alleviate these drawbacks, in this work, unlike the existing setup, an OFDMA-TDMA based wireless geophone network is proposed to maximize the throughput for timely delivery of the seismic data from geophones to the data center. Furthermore, a TV white space is utilized for transmission in order to have long-distance links between the wireless geophones and the data center, and ultimately evading the use of intermediate relays. This, in turn, reduces the delivery time of the seismic data. More importantly, the seismic data transmission is modeled using a Markov chain and analytical expressions of throughput and transmission time are derived. Finally, our theoretical findings are substantially corroborated by simulation results.
