دانلود A connection selection method for vertical handoff in hybrid wireless environment

Abstract

The  next  generation  wireless  networks  will  consist  of  heterogeneous  access  networks  from  3G  cellular,  WiFi,  WiMAX  to other emerging access technologies. To support the mobile host in  the  hybrid  overlay  wireless,  a  cross-layer  vertical  handoff  control method has been proposed. To efficiently select the optimum  network  connection,  attributes  from  the multi-layer  platform is provided to handoff decision component. The proposed algorithm is  based  on hybrid neuro-fuzzy concept with low  packet  loss  and  latency.  We  have  analyzed  our  implemented  model  under  different  scenarios.  Results  from  the  experiments indicate the advantages of the proposed scheme.
