摘要： The breadth-first search (BFS) starts with a root node. In the first stage, all neighbors of the root node are discovered and added to the nodes frontier. In the following stages, unvisited nodes from the neighbors of the frontier nodes are discovered and added to the frontier. To improve the parallelization of the BFS, the bottom-up search iterates over all unvisited nodes, where each unvisited node searches for its visited neighbors. Communication between nodes and clusters is pipelined with the execution of the BFS.

摘要： To enable lossless compression, an auxiliary bitmap is used to provide side information about the graph bitmap. Each bit in the auxiliary bitmap represents a word in the graph bitmap. A zero bit in the auxiliary bitmap means that the corresponding word in the graph bitmap is not transmitted. Therefore, it is set to the default value, λ, during decompression. This default value could be either an all-zeros word, or all-ones word depending on the BFS step. A one bit in the auxiliary bitmap means that the corresponding word in the graph bitmap is transmitted.

摘要： A position estimation method for indoor positioning includes filtering an initial position estimate that includes a corresponding covariance that reflects the quality of the geometry of the reference points and a previous initial position estimate that includes a corresponding covariance that reflects the quality of the geometry of the reference points by a Kalman filter to generate an updated previous position estimate, analyzing the updated previous position estimate to determine if the value is outside of a range, and constraining the updated previous position estimate based on the value being outside of the range.
