Research of Improved DV-Hop Algorithm in Coal Mine Monitoring Application for WSNs

摘要

DV-Hop and its improved algorithms for WSNs are analyzed.It proposes IDV-Hop(Improved DV-Hop) based on the special circumstances of coal mine.In IDVHop,every beacon node only broadcasts information within the n-hop,which reduces high communication overhead for flooding in the whole network and improves system stability.The anchor nodes are all from the least number of m anchor nodes within the nhop,which enhances positioning accuracy and meet highly the requirement of practical applications.
