摘要：Wireless Heterogeneous Networks are integrated within fourth generation recently. The 4G wireless communication system should assure a few of QoS related facilities such as offering high data rates, seamless mobility, strong RSS. When accomplishment and requisite of a user is acknowledged the system gets succeed in handoff and seamless connectivity. In such a user requisite data rate plays an imperative role in wireless networks. This paper proposes a novel method for vertical handoff in 4G wireless heterogeneous networks based on data transfer rate. In this paper distance based RSS is used as another parameter to initialize the handoff and an efficient data recovery technique is proposed. Log based recovery technique saves the logs in both mobile node and base stations for fast and lossless data recovery. Moreover, feasibility of this method is compared with existing method in terms of bandwidth and recovery time.
