Survey and Analysis of Handoff Decision Strategies for Heterogeneous Mobile Wireless Networks

Mobility is the important feature of today's wireless network. Every user expects the best service network rather than best connected network. Due to the various heterogeneous wireless network availability, users get a choice of selecting the best service network, based on various preferences. Mobility is possible due to handoff process. The typical decision making before the handoff, to select the best connected network, plays a vital role, which decides service continuity. Entire service should be aware of the roaming events. In this paper we study various proposals of handoff decision strategies, based on various parameter listed below and the state of the art analytical analysis is presented with our notations.
