Problems

Paging Cost. --- bandwidth Registration Cost. --- power and bandwidth

There is a tradeoff between these two costs

Continuation Region Conclusions

Iteration algorithm can be applied to an generalMarkov Chain

Mobile issues registration when it is not whereit is expected to be

Continuation region tends to move with mobileContinuation region tends to increase withConverge to locally optimal, but not globally
