Algorithm for Seamless Handover between Wimax and Wlan Radio Access Technology Using Ns2

چکیده
The convergence of mobile homogeneous networks to heterogeneous networks had put forth the challenge of seamless handovers between different radio access networks with maintained QoS. Efficient vertical handover decision strategy is vital for heterogeneous WiMax/WLAN networks that in return do combine advantages from both access technology in terms of data rates and coverage, offering high QoS to mobile users. As a compliment to WiMax; WLAN is used as it is designed for low range, high-medium data rate access and low mobility. An algorithm is proposed based on the speed of the mobile node, bandwidth and packet class priority for handover between WiMax and WiFi in this paper. The results showed that the channel utilization, handover latencies and average throughput has been improved with reduced packet loss.
