Jyoti Madaan, Indu Kashyap . Vertical Handoff Decision Strategies in Heterogeneous Wireless Networks. Communications on Applied Electronics. 2, 1 ( June 2015), 43-50. DOI=10.5120/cae-1652
In wireless communications of fourth generation the expectation to assimilate a hypothetically numerous heterogeneous wireless technologies are happened under consideration of a novel step toward worldwide smooth access. The advancement in wireless networks increases the challenges of mobility management as well the challenges of merging a various number of wireless networks. Out of those the main challenge for smooth movement is the accessibility of consistent vertical (intersystem) and horizontal (intra-system) handoff processes. So to improve the quality of service and to provide continuous connectivity these handoff schemes must be efficient. This paper represents various features of handoff and discusses various factors related to handoff. Hand-off management process, Hand-off types, Handoff decisions problems and Vertical Handoff decision strategies and a brief comparative review of different handoff VHD strategies is presented through tabular form.
