Most existing works on sensor coverage mainly concentrate on the full coverage models which ensure that all points in the deployment region are covered at the expense of high complexity and cost. In contrast, the exposure-path prevention does not require full coverage sensor deployment, and instead it only needs the partial coverage, because the exposure paths are prevented as long as no moving objects...
Deriving the critical density to achieve region coverage for random sensor-nodes deployments is a fundamentally important problem in the area of wireless sensor networks. Most existing works on region coverage is based on the omnidirectional sensing model, and focus on full coverage model which ensures that every point in the deployment region is covered. In this paper, we consider coverage problem...
