In order to authenticate non-existence of a resource, the DNS server will hash the requested zone-specific name component and return the NSEC3-record indicating the non-existent range to which it belongs.
My heart fluttered for just a moment, as I believed that my requested buffer zone would not be a forthcoming precaution for a transatlantic flight.
However, too small request zone can lead to no or unstable routing in the request zone, even though a stable route exists outside the request zone.
We call this "holes in the request zone".
The first is the definition and calculation of the request zone; the second is self-adaptation of the request zone.
After reaching the Destination CH, it calculates the expected zone and request zone of the node D. The request zone is given by the πR2where (5).
Expanding the request zone to the entire network when route discovery fails rapidly degrades performance and loses the benefits of an algorithm based on a confined request zone.
Gateway node calculates the expected and request zone for the destination node.
Most of the nodes in WSNHA are static, so the shape of the request zone can derive from the definition in LAR, DREAM, and LBM, but the calculation of the request zone should be appropriate to the task.
LAR [26], DREAM [27], and LBM [28] represent three request zone shapes: rectangle, bar, and fan, respectively.
The condition for determining whether is located in the Rzone is. Figure 1 Request zone in WSNHA-LBAR.
