A Fast Handoff Method Based on RSSI and LQI in Wireless Sensor Network

摘要

The thesis also puts forward a fast handoff method based on RSSI and LQI, which makes improvements on preset parameters, subnet selection, decision standards and reparation of switching failure. The new method which confirmed by the simulation not only overcomes the traditional problems in switching technology successfully, but also reduces the scanning and handoff delays, packet loss rate, improves the network throughput and prolongs its lifetime.
