A network traffic reduction method for cooperative positioning

Cooperative positioning is suitable for applications where conventional positioning fails due to lack of connectivity with a sufficient number of reference nodes. In a dense network, as the number of cooperating devices increases, the number of packet exchanges also increases proportionally. This causes network congestion and increases packet collisions. In order to maintain the quality of positioning, we need to reduce loss of information due to collisions. This can achieved by reducing the broadcast of unnecessary information. We show that by intelligently suppressing the transmission of selected nodes, the overall network traffic can be reduced without degrading the positioning performance significantly.
