Research of an Adaptive Node Deployment Technology for Multi-sensor Networks

Based on multi-sensor node circular data acquisition area form a series of similar triangle tangent in geometrical on the effectiveness and feasibility, this paper puts forward a method based on similarity triangular network node coordination control nodes deployed technology.First put data acquisition regional segmentation for multiple geometric similar, guarantee the triangle of monitoring area seamless coverage while gathered least sensor node.Secondly in cluster head nodes and clumping area between the sensor node constructing efficient topological.Then build a kind of adaptive node failure rebuild network topology control mechanism.Simulation experiments show that the nodes deployed algorithm is able to monitor the area completely seamless coverage, keep the overall performance of data transmission efficiency and reliability.
