| Abstract | Abstract — In wireless sensor network (WSNs), the cover-age strategy for achieving higher performance in intruder detection probability near irregular geographical obstacles inside a military terrain, is studied in this paper. The real life problem of the of intruder detection near irregular geographical obstacles has not been focused so far, in which coverage requirement is very high, hard and expensive, if we require the entire boundary of an obstacle in the region has to be covered. Therefore, a novel coverage problem based on data fusion detection system, called Trail Coverage is proposed in this paper. A sensor network with Trail Coverage provides higher performance rate in detection probability of any intruder that moves along the shortest passes between the geographical obstacles inside a military terrain. We consider various preliminary steps to provide a strong basement for this Trail Coverage model. We state a probabilistic model to locate the obstacles inside the region, with randomly deployed sensor nodes, during initial network configuration. Based on computational geometry techniques we design a O1 − Continuous Obstacle Hull to find the trail region between the obstacles, for the node deployment, to achieve Trail Coverage. We adopt fusion based target detec-tion technique to obtain effective performance in intruder detection probability at the trail region. Through analytical results, we show, the significance of the Trail Coverage strategy to meet the desired performance requirements of an intruder detection system, while maintaining greater network coverage with a given fusion range. |
