A small-scale wireless transmission network attached to large-scale seismic acquisition and recording system

Large-scale Seismic Acquisition and Recording System (LSARS) is one of the most important equipments in geological exploration. This paper describes a LSARS which contains both wired and wireless nodes. Wired node as the center, with a number of wireless nodes arranged around it, a small wireless transmission network is formed. A hierarchical network structure and a flooding algorithm with direction are designed and implemented for the wireless transmission network. Experimental tests show that the wireless transmission network can meet the requirements of the system.
