The design goal of Fourth Generation (4G) networks is to offer seamless connectivity across existing wired and wireless access technologies under the ‘‘Anywhere, Anytime’’ paradigm. Emerging IEEE 802.21 supports optimization of vertical handoffs amongst heterogeneous access networks under the umbrella of 4G. This paper investigates the IEEE 802.21 based(More)
Internet has entered in our lives in a big way, from sending mails, reading the news, to the booking of tickets on-line, it has a special role in every one’s life. There is a great need in the near future to take the Internet to the remote places in our country, where network infrastructure is not in place. Many efforts are made in this direction and one of(More)
In broadband wireless access network, continuous high speed data communication can be provided to mobile subscribers by well designed mobility management, where handover is a key element in maintaining air link to base station even in high velocity. When a mobile station changes its geographical position, it may also need to change its attachment point in(More)
Received Signal Strength based (RSS) horizontal handoff algorithms have been most commonly used by nearly all second generation and third generation wireless networks in a homogeneous environment. Vertical handoffs or network selection algorithms are the terms coined due to integration and interoperability of existing wired and wireless access networks(More)
Terminal mobility with Quality of Service (QoS) can be provided through efficient and seamless handoffs and handoff management procedures in 4G wireless access networks. The primary objective of this work is to analyze the handoff management procedures within a WiMAX access networks and to evaluate its impact on different QoS metrics such as Packet Loss,(More)
