Accumulation point model for barrier coverage

The reliability and fault tolerance problems are very important for long strip barrier coverage sensor networks. We propose an economical, robust and reliable deployment model, called Accumulation Point Model (APM). A localized algorithm is presented to build the accumulation point k-barrier coverage. In our network simulation, the network lifetime of APM is much higher than random point barrier coverage model. Compared with independent belt barrier coverage model, APM exhibits good failure tolerance.
