Abstract
A new method based on coherent combining of neighboring wireless node emitted fields is proposed for information transmission in wireless sensor networks. Coherent combining allows extending transmission range and can be used to increase the coverage zone and to solve the problem of network low connectivity in case of nonhomogeneous distribution of wireless nodes. A computer model of the sensor network with collective information transmission has been developed. A numerical analysis of the suggested method efficiency based on the study of the network connectivity has been carried out. The possibility of sensor network life extension by this method has been demonstrated.
