Hierarchical Optimization Handoff Algorithm
- Handoff Threshold (Ht) :When the mobile’s signal crosses the handoff threshold Ht of it’s current BS, a handoff request is initiated.
- Critical Threshold (Ct) : When the mobile’s signal below the critical threshold Ct of its current BS, the received signal is too weak to maintain communications between the mobile and BS, and,hence,the call must be terminated if it cannot find a new channel to support it.
