Enhanced security algorithm with key exchange protocol in wireless network

In this paper, the proposed attack detection scheme in QOS security architecture with elliptic curve Diffie-Hellman (ECDH) protocol to overcome the attacks IMS (IP Multimedia Subsystem) and Femto cell access points (H(e)NBs). Initially, it refers the current security threats and security standards in WiMAX and LTE networks. Both networks WiMAX and LTE are Fourth Generation (4G) wireless technology with well-defined Quality of Service (QOS) and security architecture. In LTE network, the present theoretical analysis of proposed scheme gives a good performance and experimental results in means of throughput, latency and frameless that are compared and analyzed with testbed implementation and simulation approaches of LTE.
