Abstract
A wireless network infrastructure, comprising static and roaming mobile nodes (including one or more types of access-points), avoids unnecessary handoffs and unstable RF regions, and enables at least selected context-aware-capable mobile nodes to provide context-aware services to connected clients. More particularly, each of at least selected static nodes is enabled to provide the context-aware-capable mobile nodes with context information regarding the static node's relative position and direction, details of information served by the static node, special flags indicative of relevant impending changes in the foregoing parameters, and a range of signal strength values defining a stable RF zone for associated mobile nodes. Each context-aware-capable mobile node accordingly creates a context map that at least in part enables determination of the mobile node's next change in static node association and the preferred timing for the change.
