摘要：Internet of Things (IoT) is identifiable objects uniquely and their representations of an IoT are likestructures. The concept of IoT is to develop the information in sense. And the device interacts without the need ofhuman. Zigbee is a communication protocol and it is used to transmit data over long distances by passing data throughthe intermediate devices to cover longer distant. ZigBee is the emerging standard for ad hoc networks based on IEEE802.15.4. It provides secure networking and can be used anywhere at any time. It can be easily implemented with anytype of wireless generation and It requires less power to operate. 4G (Fourth Generation) is the next generation ofwireless networks and it can secure data transfer. Speed of 4G provides fast and it can be achieved by OFDMmodulation. World Wide Interoperability for Microwave Access (WiMAX) is wireless technology and it provideswireless data over longer distance. It provides a media access control (MAC) and the proposes is full range of securityfeatures to secured the data exchange. It nearly transmits the data at 70 Mbps. In this paper, Zigbee Wireless sensornodes real time data transmission integrated with 4G Technology using tree routing for long distance SecureCommunication with high mobility and it is proposed and analysed by using OPNET. Tree routing is used to find thenext hop knob for a given destination address without routing tables. Still, a sender cannot know that the destination issituated close by or if it is not in the sub-tree. Even though the tree routing is capable in the observation point ofmemory usage. The concert such as Jitter, data sent, delay and packet delay variation and end-to-end delay aresimulated.
