A handover security mechanism employing the Diffie-Hellman key exchange approach for the IEEE802.16e wireless networks Abstract. In this paper, we propose a handover authentication mechanism, called the handover key management and authentication scheme (HaKMA for short), which as a three-layer authentication architecture is a new version of our previous work, the Diffie-Hellman-PKDS-based authentication method (DiHam for short) improving its key generation flow and adding a handover authentication scheme to respectively speed up the handover process and increase the security level for mobile stations (MSs). AAA server supported authentication is also enhanced by invoking an improved extensible authentication protocol (EAP). According to the analyses of this study the HaKMA can effectively and efficiently provide user authentication and balance data security and system performance during handover.

“…Another fast handover approach to minimize the blocking time of real-time traffic is presented in [26]. The paper proposes a novel IEEE 802.16e network architecture for reducing the handover time, which is still compatible to the IEEE 802.16e standard.…”

“…The paper proposes a novel IEEE 802.16e network architecture for reducing the handover time, which is still compatible to the IEEE 802.16e standard. The performance analysis provided in [26] calculates the mean time to send ranging request message (RNG-REQ) in a contention-based ranging phase. The main drawback of the proposed analysis is the assumption of failure rate to send the RNG-REQ in the ranging procedure, as an independent variable.…”

The IEEE 802.16 standard for mobile broadband wireless access specifies a contention based handover (HO) procedure for its mobile users. There are many HO parameters defined by the standard, which need a fine tuning in order to achieve a satisfactory communication performance. This article presents a precise mathematical model for calculating the impact of handover parameters and an error-prone radio channel over the performance of IEEE 802.16 handover procedure which uses Code Division Multiple Access (CDMA) ranging codes. We analytically analyze the handover latency and handover connection dropping probability. The results are compared with experimental measurements conducted on a protocol prototype developed by using Specification and Description Language (SDL). The following parameters are investigated: values of the minimal and maximal contention window size, number of transmission allocations per frame, number of available CDMA ranging codes, timers and maximum retransmission limits used in the processes of ranging, basic capabilities negotiation and registration. We have found that all parameters need to be carefully adjusted in accordance to the network conditions: number of stations performing handover at a same time, WiMAX physical layer working parameters, and frame-error rate in the uplink and downlink radio channel.

“…In [4], new schemes including target BS selection, fast synchronization and association, and optimized handover initiation timing were presented to reduce the layer 2 handover delay. In [5], a network assisted fast handover scheme using the fast association and fast network re-entry methods was proposed to improve the layer 2 handover. These two studies focus on reducing the link layer latency.…”

The IEEE 802.16 standard was designed to
provide rapid deployment, high bandwidth, and low-cost
fixed broadband wireless access (BWA). As an enhancement,
IEEE 802.16e standard was developed for further
supporting mobility. As media streaming services are
extending to mobile stations, it is crucial to minimize the
handover delay and service disruption time so as to
maintain the sustained connection of IP sessions. In this
work, we propose a cross-layer IPv6 fast handover scheme
which features integrated layer 2/layer 3 messages and fast
network re-entry methods. Compared with the fast mobile
IPv6 over 802.16e network scheme in predictive mode, our
proposed scheme can reduce the service disruption time by
more than 90% and 85% for downlink and uplink,
respectively so that the quality of service (QoS) for real-time
applications can be improved significantly
