Abstract Current HandOver (HO) mechanism usually cuts down the duration of service interruption by pre- executing some preparation operations before HO execution. But this technique is much dependant on mobility trace prediction algorithm, which is very difficult in actual environment. To resolve this problem, a novel HO mechanism based on Cooperative Diversity (CDHO) is proposed. CDHO introduces cooperative diversity between Mobile Node (MN) and source Base Station (BS) to extend the service duration in which source BS can satisfy MN’s QoS requirement. In this extended duration, MN has much more time to finish HO preparation, thus CDHO reduces dependence on mobility trace prediction algorithm.
