Markov-based vertical handoff decision algorithms in heterogeneous wireless networks

- Our work has considered the QoS factors and constructed a reward function to model the QoS properties.
- Our work has considered MT's velocity, network access cost and switching cost for vertical handoff decision.
- We have applied G1 and entropy methods to calculate the weight of each QoS factor in the reward function.
- By taking the MT's velocity into consideration, our work can avoid unnecessary handoffs.
