Abstract :
The design of handoff algorithms for cellular communication systems based on signal-strength and distance measurements is studied within a hybrid system framework. It is shown that a previously proposed algorithm which trades off between the expected number of handoffs and the expected number of signal degradations suffers from excessive handoff delay. Therefore, the optimal tradeoff between handoff delay and number of handoffs is investigated. The corresponding suboptimal algorithm provides near ideal performance: exactly one handoff and no delay
