One of the main goals in the design of Next Generation Wireless Networks is the possibility to keep the connectivity of a user while it moves among heterogeneous networks. The IETF (Internet Engineering task Force) has designed some protocols in order to solve this problem. One of them, Mobile IP, has been chosen as the core mobility management mechanism for wireless LANs and 4G cellular networks. One of the most critical stages of the mobility process is the handover management. The high delay of this phase is a limitation to seamless mobility. In this work, a detailed analysis about handover process has been presented. Moreover, movement detection is a very costly stage in handover mechanism so a new fast movement detection algorithm to improve this detection has been developed, called FDML3 (Fast Detection Movement Layer 3). Through the simulation of the algohoritm, the benefits of the proposed algohoritm have been shown in terms of handover latency compared to Mobile IPv6 mobility management protocol.
