Abstract: Nowaday's mobile telecommunication placed a crucial role for making the effective communication, data, voice, images and video transfer. For these multipurpose, telecommunication effectively utilize the different generation of networks. Among the various generation, 4G Long Term Evolution (LTE) has been widely utilized in present technology. The developed 4G/LTE is developed by increasing the previous generations functionality. Even though the 4G transmit the information very fast, the network has facing several problems such as intermediate attacks, vulnerabilities and the Quality of Service (QoS). These vulnerabilities are overcome by applying the first publicly reported practical protocol with handoff management hierarchical IPv6 protocol for eliminating the intermediate attack. The first publicly introduce practical approach examines the network in semi, active and passive LTE for eliminating the intermediate attacks. In addition, the handoff management process maintains the connection between the nodes and Quality of Service (QoS) while moving from one access point to another using the hierarchical IPv6. The first publicly reported practical protocol with handoff management hierarchical IPv6 protocol is implemented using the software (Intel i7 processor and Ubuntu 14.04 OS) and hardware configuration (USRP B210 device) and the system ensures the effective results which is done by using the experimental results and the system achieves high security such as 96.45% with minimum time 6.98 msec.
