[GWV12] A Range-Free Localization Protocol for Wireless Sensor NetworksConférence Internationale avec comité de lecture : IEEE ISWCS2012, August 2012, pp.Ã paraitre,Mots clés: wireless sensor networks, range-free localization, DV-hop protocol, simulation, performance analysis
Résumé:
Localization is a fundamental issue for many wireless
network applications. Without additional ranging devises, the
range-free localization scheme offers a cost-effective solution for
low-cost indoor sensor networks. As a typical range-free
algorithm, DV-hop (Distance Vector - hop) algorithm has the
advantage to localize normal nodes that have less than three
neighbor anchors. In order to implement the DV-hop based
algorithms in network scenarios, we create a new DV-hop
localization protocol. This new protocol is presented in this paper
with details, including the frame formats, the improvement of
medium access method, as well as parameters used in deciding
the end of each DV-hop step. Finally, using the new localization
protocol, we investigate into some DV-hop algorithms (DV-hop,
Checkout DV-hop and Selective 3-Anchor DV-hop) in terms of
localization accuracy and synchronization. Simulation results
show the good performance of our localization protocol.
