The most important issues in wireless and mobile communication technologies are to provide seamless handover when a Mobile Node (MN) moves between different access networks. The present communication reveals a survey of different handovers within WiMAX and WLAN and also reviewed the various seamless handover solutions. The solutions are compared based on a list of criteria such as handover latency, handover type, complexity, dropped packets, duplication of events and scalability to provide a better QoS. The comparison reveals the advantage and disadvantages of each scheme to achieve seamless handoff in next generation wireless networks.
