A better understanding of the spatial structure of existing opportunistic wireless network deployments will offer new insights for future deployments, e.g. dense femtocell networks. In this paper we present a performance analysis for three different localization algorithms that support such efforts by finding the location of IEEE 802.11 Wi-Fi access points (APs) from distributed signal strength measurements...
The design of emerging multi-tier dense wireless networks, which integrate opportunistically deployed devices into legacy infrastructure networks, will hugely benefit from a thorough understanding of the spatial structure of existing large-scale unplanned deployments. However, detailed and precise datasets which would enable acquiring such knowledge are unavailable and non-trivial to generate. In...
In this paper we investigate a novel distributed channel allocation method for cognitive radio networks (CRNs), which is based on a grid quorum system. The objective of this paper is twofold. First, the paper studies a grid-based quorum arrangement, also used by power saving protocols. Second, it proposes two channel mapping methods based on a grid quorum and sub-grids. Each node visits channels according...
