Abstract :
Existing soft handoff techniques lead to plenty of out-of- sequence packets during downward vertical handoffs (DVHOs). In this paper, we present two new network-layer soft vertical handoff schemes, called SHORDER and E-SHORDER. The former can prevent mobile nodes from receiving reordered packets during DVHOs with a low overhead. The latter further hinders their correspondent nodes from receiving out-of-order packets caused by mobile nodes´ DVHOs. Then, we analyze the performance of our proposed approaches. By experiments, we show that they have a good effect in practice.
