Design and implementation of an improved Mobile IPv6 protocol

According to the standard mobile IPv6 proposed by IETF, a mobile node must update its home agent and correspondent nodes whenever it moves to a new position in foreign networks. This must result in the high binding and sending cost, as well as the degradation of network performance. In this paper, an improved mobile IPv6 protocol is presented, which can reduce the binding cost by dividing binding update of the mobile nodes into the home update and the local update, and therefore improve the performance of the network.
