Plenty of new routing protocols have been presented to overcome the difficulty in applying the routing protocol which was proposed for the existing wireless networks (IEEE 802.11) to WSN. Therefore, this paper presents the wired and wireless integrated networks which transmit the information collected from the wireless sensor networks to wired networks via WSN Gateway. At this time, this paper embodies the Zigbee protocol in the wireless networks based on the 802.15.4 standard and designs an advanced routing protocol for wired and wireless integrated networks by modifying the existing ad hoc routing protocol to enable access to wired networks such as the internet. Moreover, we design an integration method which is based on WSN Gateway which integrates two different networks efficiently. To evaluate the proposed research, we simulated an advanced routing method and WSN Gateway in the wired and wireless integrated networks using the NS-2 simulator.
