Traditionally, signal-to-noise ratio of a mobile determines the handoff dynamics of the mobile. But in certain cases, precise location of the mobile augmented by information services, such as IEEE 802.21 MIS, can expedite the handoff with similar per

In a mobile environment, as a mobile node moves from one point of attachment to another during an ongoing application session it is subjected to packet loss due to network and link layer transition. Such packet loss affects the quality of ongoing com

We provide an experimental analysis of MIMM (multi-interface mobility management) demonstrated in a heterogeneous network involving 802.11b and CDMA access technologies. We have experimented WAN-LAN handoff for real-time service (voice and video) in

Emerging mobile devices often want to discover neighboring networks in real time. For example, a mobile may want to know the capabilities of the surrounding WiFi networks so that it can inteliigently determine which one to use next and avoid wasting
