LTE-A is a standard for wireless communication developed by 3GPP LTE release 10, which enhances the existing LTE network for supporting higher data usage, low latencies and better spectral efficiency. Security is the one of the challenge in LTE-A network. Some security risks are modification, injection and eavesdropping attacks. Another challenge in LTE-A network is resource utilization. Due to the multiple key management mechanisms, the complexity of LTE-A network is increase. An existing system utilized Elliptic Curve-Diffie Hellman Key Exchange algorithm which establish a shared secret key over communication channel. The drawbacks of ECDH are computational cost and communication cost is relatively high. In this paper, we propose an efficient key distribution technique called Quantum Key Distribution. This technique improves the security as well as utilizes the resources effectively. The proposed scheme includes BB84 protocol, which uses the properties of quantum mechanism for detecting attackers and unconditional security. Using this system we achieve maximum security level compared with existing technique.

In wireless networks, to provide quality of service by means of resource allocation the protocols need to be evaluate a lingering bandwidth estimation for further allocationHowever, there is no standardized mechanism or method has been proposed to accurately evaluate the amount of available resources on a given channel. Such an evaluation would, lead to optimize bandwidth utilization for applications of mobile adhoc networks like multimedia dataflow. We proposes a new techniques to estimate a bandwidth of a node in IEEE 802. 11 based mobile adhoc networks. We show by simulations that our technique provides we show by simulations that our technique provides an accurate estimation of the lingering bandwidth on wireless links in many ad hoc configurations and an efficient delivery ratio & reduce delay time in the environment.
