Abstract

The integration of diverse wireless technologies is the emerging trend in providing ubiquitous access to the high data rate wireless network. Currently, in 4G networks, new mobile devices aim to provide the user with great flexibility and connectivity for network access but also generate the challenging problems of mobility support among different networks. Users expect to continue their connections without any disruption when they move from one network to another by the process handoff. In this paper, bandwidth based handoff algorithm for multiple heterogeneous wireless networks are developed. The wrong decision handoff probability is major problem in 4G wireless networks. Wrong decision handoff probability is calculated based on proposed bandwidth based handoff algorithm and the performance of the proposed algorithm is estimated.
