Seismic communication might promise to revolutionize the theory of seismic waves. However, one greatest challenges its widespread adoption is difficulty signal extraction because waves in vibration environments, such as seas, streets, city centers and subways, are very complex. Here, we employ segmented correlation technology with Morse code (SCTMC), which extracts target by cutting collected data into a series segments makes these cross-correlate decoded process data. To test effectiveness...
A rectangular array of seismic nodes is called a 3D sensors which suitable for geographic routing. However, when certain have no location information, using detours or other methods to detect the path will increase latency and power consumption It challenging maintain high performance routing in practical exploration networks. This letter proposes greedy flee direction algorithm (GFDR). According feature that intersection connection set not empty, GFDR can drive packet continuously forward...
