We all know the quick development in the wireless network area during the last decade and the importance of using sensors technique in our daily life. Specially, after the IoT revolution, but we all know some of the troubles that sensor faces, such as the littleness of energy resulted from its small size, which determines a small proportion of battery owned by each node of the sensor. In this paper we try to mitigate the burden that sensor nodes hold, whether a conventional sensor, cluster node or even Sink node as well as we try to improve the Sensor Networks data forwarding to the central BS and processing center by utilizing new protocol for connecting the sensor nodes directly to Wi-Fi Access Points connecting through ZigBee (SZW). This act as a gateway through bridging over the data from TCP/IP compact ZigBee compact and applies a different way. We called this process (Sensor ZigBee Wi-Fi connecting) SZW technique that will extend the life time of the network improving its operation and performance. Our results and simulation presented the effectiveness of the SZW protocol compared to previous techniques.
