As a consequence of Needs to continue in terms of data rates, speed and quality of service, various
aspects of wireless networks are evolving. In the same network or across different technology and service provider
networks, those aspects must be adaptable. Worldwide interoperability for microwave Access (WiMAX) is also one
of the networks of the future century (4G) That requires additional research. However, the handoff structure that
concerns the transition of mobile stations within the scope of network from one base station to another similar
homogeneous network (horizontal handover) or various heterogeneous network (vertical handover) is a major
consideration for WiMAX to achieve mobility. In the current context, this article discusses the characteristics of
WiMAX, Concentrate on possible handoff-related study problems, generally addressing the two forms of handover.
this essay concentratemore On homogeneous performance of handover . In WiMAX, mobility aspects are defined
as an individual layer of the Mobility Agent (MA), above its MAC layer, and some indication of a network layer.
