Powder particles of polystyrene insulation system construction plan
undingBox algorithm is fully distributed and requires only a relatively small amount of communication and a simple calculation , has good scalability . DV-hop algorithm requires relatively small proportion of the anchor nodes , moderate amount of computing and communications , but limited by the distribution of nodes , the node 's hardware requirements for the low , simple . The rules in the intensive implementation of the network layout works well , but in sparse or irregular networks , the use of distance instead of jumping straight-line distance , the positioning accuracy down to communication radius , there is some error. BoundingBox centroid algorithm and the amount of computation and communication are very small , and only receive messages ( receiving more than sending a low energy consumption , in line with the requirements of low power sensor networks . using a distributed local formula,p90x workout calendar, good scalability , positioning time Delay has nothing to do with the network size . But the two algorithms is a typical sparse anchor node problem by limiting algorithms , positioning accuracy is heavily dependent on the density and distribution of anchor nodes . 【
