Integrating Heterogeneous Wireless Networks By Soft And Hard Handoff

Wireless technology eradicated the networks that use cables. Wireless networks use microwaves and other radio signals for communication. One of the basic requirements is to support seamless mobility in wireless networks. Seamless means smooth transition, such that user does not perceive any delay or interruption of service. The main objective is to design a handoff decision criterion suitable to the situation. The purpose of the handoff is to keep continuous or seamless service to mobile users through different cells or network coverage It is consequently of special importance for wireless networks. This work uses soft and hard hand off for implementation.
