Mobility of CN is envisioned in such a way that CN1 is in phase with CN3 and CN2 is in phase with CN4. Initially CN1 and CN3 are at bottom end of their respective elliptical paths and CN2 and CN4 are at the top end of their corresponding elliptical paths. Every node moves in clockwise direction and reaches to next destination after time Ti/4. In this way a node in its one revolution has four points to stop each after phase angle of θ/2. Their motion is synchronized in such a way that when CN1 is about the top. Each node moves upward to their predefined destination, transfer data to next CN, and move back to initial stage. This motion pattern is synchronized in such a way that when a certain courier node is about to reach its destination next forwarder has just started its tour, first node find next CN to take its data to next CN.
