Abstract

The invention discloses a method for judging a boundary node of a wireless sensor two-dimensional network, relates to the field of wireless sensor node detection, and comprises the following steps: 1) determining all nodes in the wireless sensor two-dimensional network; 2) judging all the nodes included in a node One-hop neighbor nodes; 3) Among the one-hop neighbor nodes of any node, choose one one-hop neighbor node as the initial node to perform depth-first search until all the one-hop neighbor nodes in the set are searched; 4) Depth-first judgment Search the path detected: if only one path is detected by the depth-first search, directly determine whether the path forms a closed loop; Form a closed loop; 6) judge whether the detected node u is surrounded by the closed loop n ; The present invention can be completed at the local end, requires less calculation, and efficiently judges whether the detected node is a boundary node.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a method for judging boundary nodes of a wireless sensor two-dimensional network. Background technique [0002] Now, wireless sensor two-dimensional networks (WSNs) have been widely adopted to collect physical information about regions of interest (RoIs). Especially in areas with harsh environments that cannot be reached by humans or are not easy to stay for a long time, a series of detections can only be performed by arranging sensor nodes. Therefore, it is very important to use a two-dimensional network of wireless sensors to detect information. Especially in some applications, such as environmental observation, forecasting system, animal number detection, etc., network coverage is a very important factor, and boundary detection is also very important. Physical coverage represents the detection capability of a two-dimensional wireless sensor network, and coverage is one...
