Improving the Lifetime of Non-penetrable Barrier Coverage in Sensor Networks

  title={Improving the Lifetime of Non-penetrable Barrier Coverage in Sensor Networks},
  author={Jorge Arturo Cobb},
  journal={2015 IEEE 35th International Conference on Distributed Computing Systems Workshops},
An area covered by a wireless sensor network is protected, or covered, by a sensor barrier if there exists a subset of sensors that divide the area into two regions, such that no intruder can move from one region into the other without being detected. To maximize the length of time the area is covered by a barrier, the sensors can be divided into multiple disjoint subsets, where each subset is a barrier. By having only one barrier active at any time, the duration of the coverage is maximized… CONTINUE READING
