Abstract

An HWN consists of different wireless networks. A heterogeneous network (HWN). Efficient handoff (HO) systems are needed to improve service quality (QoS) and provide a reliable environment in order to ensure seamless mobility across HWN. Optimum vertical handoff (VHO) in such an environment is a difficult problem. VHO decisions are based on the measurements of received signal strength ( RSS). HO decisions are taken separately without taking other HO user (EU) equipment into account. This leads to higher block rates and higher mobile device consumption. The VHO decision requires lower speeds, and since a high speed user can cause an inutile handoff that will waste network resources and thus affect network QoS. User mobility is a very vital factor in the decision to use VHO. By examining EU speed when deciding on a HO, the transmission cost and transmission time can also be reduced. The VHO prediction approach based on the mathematical model uses well established objective functions that take into consideration RSS, EU speed, load and user bandwidth cost. By adjusting the weights in the defined objective function, the system performance can be improved according to user preferences. Because of the great bandwidth and ease of networking, we take Wi-Fi and Wimax into account.
