- Comparison Between Vertical Handoff Decision Algorithms for Heterogeneous Wireless Networks
- The next generation wireless networks will support the vertical handoff mechanism in which users can maintain the connections when they switch from one network to another (e.g., from IEEE 802.11b to CDMA 1xRTT network, and vice versa). Although various vertical handoff decision algorithms have been proposed in the literature recently,...

- Impact of Layer 2 Behavior on TCP Performance in WLAN
- Ubiquitous networks enabling access by Mobile Nodes MNs at any time and at any location will consist of several different Wireless LANs WLANs, so it is likely that an MN will traverse several WLANs during communication. In such a case, avoiding performance degradation during the handoff becomes a critical issue....

- Multi Layer Rules Based Framework for Vertical Handoff
- Seamless interoperability between two dissimilar networks require handoff from one network to the other. Such handoffs are known as vertical handoffs. Vertical handoff introduces a shift in the approach to handoffs. It deals with handoffs between dissimilar networks, such as from an access point to a base station or vice...

- HAMS: Layer 2 Handoff Accurate Measurement Strategy in WLANs 802.11
- The layer 2 handoff latency in WLANs 802.11 has traditionally been measured as the time between the first probe request message sent by the mobile station and the arrival of a reassociation response message from an access point. However, that measure does not represent the time the station remains disconnected...

- A New Prioritized Fast Handoff Protocol for Mobile IP
- Mobile IP protocol has been designed to handle global and seamless user's mobility on the Internet. However, Mobile IP suffers from handoff latency due to slow handoff discovery and binding association notification. To reduce this latency, the paper proposes a new handoff protocol where it attributes a high priority to...

- Using Fuzzy Logic to Mitigate IEEE 802.11 Handoff Latency
- Multimedia transmissions are delay sensitive Internet applications. Because mobile stations move all of the time, handoff processes are necessary and unavoidable in wireless network environments. Since handoff processes tend to break the communication link, some researches have been done to reduce the break time and arrival delay during Internet multimedia...
