A Handoff Technique to Reduce False-Handoff Probability in Next Generation Wireless Networks
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 3
Abstract
Next Generation Wireless Systems (NGWS) include o-existence of current wireless technologies such as WLANs, WiMAX, General Packet Radio Service (GPRS) and Universal obile Telecommunications System (UMTS). The most important and challenging issue is seamless handoff anagement in NGWS to ensure the Quality of Service (QoS). n this article, we propose a GPS based handoff technique to mprove handoff probability in NGWS. Using GPS we etermine the direction of velocity of the MT (Mobile erminal). In earlier works handoff based on Relative Signal trength (RSS) of BS (base station) was proposed. But in the case when a MT is moving towards an NBS whose RSS is less than that of its adjacent NBS, to take the decision of handover quite decisive. But using GPS we can ensure fficient and-off. The result shows that the proposed approach can solve the roblem and helps to take the right decision ecreasing false hand-off initiation probability.
