摘要：Node deployment is the key problem of wireless sensor network technology in application.The existing study on deployment of deterministic perceived nodes is simplified to the randomlydeployment. In this paper, we take the effective coverage , connectivity and probability threshold as theevaluation indices to analyze the different deployment models. Experimental results demonstrate thatthe effective coverage area of the triangle deployment is the largest when using the same number ofnodes; and if the probability is less than limits, tile deployment does not need to increase the node toensure coverage. The research results of this paper provide an important reference for the deploymentof the directional sensor networks with the given parameters.
