A review of vertical handoff algorithms based on Multi Attribute Decision Method
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 6
Abstract
Abstract - Next Generation Wireless Networks (NGWN) consists of heterogeneous networks with the support for vertical handoff. Hence vertical handoff algorithms (VHA) are the key components of NGWN. The vertical handoff decision may depend on the bandwidth available for each wireless access network, cost for accessing network, the power usage requirements, user preference, Quality of Service (QoS), and security. Hence vertical handoff decision may be solved using multi attribute decision making (MADM). Multi attribute decision making (MADM) problems involve ranking or evaluating a finite number of alternatives with multiple, attributes. There are several vertical handoffs decision algorithm proposed in the literature based on MADM techniques. In this paper we provide a overview on existing MADM algorithms for vertical handoff.
