- This paper sets forth an adaptive timer handoff algorithm with respect to the shortcoming of fixed timer handoff algorithm. In the algorithm, the real-time handoff timer value T is calculated based on the distance di between current mobile station and original serving cell as well as three constant variables: rank, ram and p, thus changing the handoff waiting time in real time. The simulation results showed that: the handoff occurs only when the mobile station needs to move to a far position from the original serving cell in the fixed timer handoff algorithm and larger set timer value T, and the strength of signals received by the mobile station in the original serving cell is poor; however, in the adaptive timer handoff algorithm, the ping-pong effect can be eliminated, the average handoff times are reduced, the mean strength of signals at handoff is better, the handoff position concentrates rationally and the overall performance reaches to the optimal effect.
