A Novel Handoff Algorithm Of Wireless Communication For Multi-tier IP-based Network

Abstract

Most of multimedia services were provided by Internet. The developments of wired network technologies are significant rapidly, such as the IP-based network. These technologies can be used to develop wireless communication network directly. The combination of wired network and wireless network could be used to access data mutually. In this paper, the multi-tier architecture is based on IP network. Recently, there are many communication systems brought up in order to offer every state’s mobile users with the best services. However, mobile users are not always in the same state. In economic benefits, it’s very inconvenience, if one uses more than one system, he should carry more than one MH at the same time. Therefore, combining all systems in a multi-tier IP-based network and disposing stratum dynamically for mobile user become a solution of such situation. Besides, we hope to reduce the frequency of handoff and increase the using rate of resource in multi-tier architecture. Therefore, in this paper, a handoff algorithm of Multi-tier IP-based network has been brought up for wireless communication. The handoff algorithm of multi-tier wireless communication is divided into two parts that are old-tier and new-tier priority algorithm. Making the programs for simulating, and then making sure that the algorithm is workable and modifying the algorithm. The results of simulation show 11.99% of handoff frequency has been decreased and 8% of using rates of resource has been increased.
