异构无线网络中基于SAW和TOPSIS算法的可信网络选择
Trusted Network Selection using SAW and TOPSIS Algorithms for Heterogeneous Wireless Networks
摘要：
无缝连续性是第四代无线网络（FGWNs）的主要目标，为了实现无缝连续性，需要使用“切换”技术，当移动终端（MT）处于重叠区域时，主要使用切换机制来实现业务连续性。在异构无线网络中，主要的挑战是不同的网络，如WiFi，WiMax，WLAN，WPAN等之间的连续连接。在本文中，垂直切换决策方案进行了比较和多属性决策（MADM）是用来选择最好的网络从可用的访客网络（VT）的移动终端的连续连接。在我们的工作中，我们主要集中在切换决策阶段，以减少切换期间的处理延迟。利用NS2对多属性决策算法SAW和TOPSIS进行了比较，以减少加工延迟。
英文摘要：
Seamless continuity is the main goal in fourth generation Wireless networks (FGWNs), to achieve this "HANDOVER" technique is used, when a mobile terminal(MT) is in overlapping area for service continuity, Handover mechanism are mainly used. In Heterogeneous wireless networks main challenge is continual connection among the different networks like WiFi, WiMax, WLAN, WPAN etc. In this paper, Vertical handover decision schemes are compared and Multi Attribute Decision Making (MADM) is used to choose the best network from the available Visitor networks (VTs) for the continuous connection by the mobile terminal. In our work we mainly concentrated to the handover decision phase and to reduce the processing delay in the period of handover. MADM algorithms SAW and TOPSIS where compared to reduce the processing delay by using NS2 to evaluate the parameters for processing delay.
