Background. The article describes an operational calculation method of the intermediate points' coordinates of the flying information robot (FIR) route, which collects information from mobile sensors of a mobile wireless sensor network.

Objective. The purpose of the paper is to develop a method that allows building the movement trajectory of the LIR, minimizing the time for collecting information from mobile sensors.

Methods. The quickly calculating method of the route' coordinates of intermediate points involves setting a quasi-mobile mode of sensors movement and the consistent use of algorithms for solving the navigation problem, the clustering problem, and the problem of finding the flying trajectory around information collection points from mobile sensors clusters that formed at the time of the start of collecting information.

Results. A method has been developed that uses the procedures of quantitative calculation of the indicators of the structural-information connectivity of wireless sensor networks with mobile sensors. These indicators take into account the presence of not only a structural connection, but also a guaranteed information exchange between a given sender-destination pair.

Conclusions. The developed method makes it possible to improve the indicators of the structural-information connectivity of wireless sensor networks with mobile sensors: k-connectivity and network bandwidth.
