Future wireless networks must be able to coordinate services within a diverse network environment. Next generation wireless network is envisioned as a convergence of different wireless access technologies providing the user enhanced connection any where any time to improve the systems resource utilization. In such converged systems, co-existence of heterogeneous access technologies with largely different characteristics like data rate for cellular network (2 Mbps), WLAN 802.11b (11 Mbps) and HIPERLAN (54 Mbps) results in handoff asymmetry that differs from the traditional intra-network handoff (horizontal handoff).
