The k-Barrier Coverage Mechanism in Wireless Mobile Sensor Networks
Chih‐Yung Chang, Chih-Yao Hsiao, Yu-Ting Chin · 2014
The k-Barrier Coverage is known as the problem of detecting the intruders by at least k sensors when the intruders moving along the crossing paths from one boundary to another. This paper proposes a barrier coverage mechanism for Wireless Mobile Sensor Networks (WMSNs). At the network initialization phase, all mobile sensors move in a distributed manner for constructing the k-Barrier Coverage. The paper aims at prolonging the barrier lifetime while achieving k-barrier coverage. Experimental study reveals that our proposed k-barrier coverage approach outperforms existing related schemes in terms of the energy consumption of mobile sensors participating in the k-barrier defense curve.
