Recently, there are many communication systems brought up in order to offer mobile users with the best services. Combining all these systems in a multi-tier IP-based network is an important issue. In this paper, we propose a novel handoff algorithm of wireless communication for multi-tier IP-based network; the handoff algorithm is divided into two parts which are Old-tier and New-tier priority algorithm. The results of simulation show 11.99% of handoff frequency has been decreased and 8% of using rates of resource has been increased.
