| 英文摘要: |
| To alleviate the localization error introduced by irregular sensor network deployment, a new mobile path localization based on key nodes (MPLPK) protocol is proposed. It can recognize all concave/convex nodes in the network as fixed anchor nodes, and simplify the following localization process based on these key nodes. The MPLPK protocol is composed of three steps. After all key nodes are found in the network, a mobile node applying improved minimum spanning tree (MST) algorithm is introduced to traverse and locate them. By taking the concave/convex nodes as anchors, the complexity of the irregular network can be degraded. And the simulation results demonstrate that MPLPK has 20% to 40% accuracy improvements than connectivity-based and anchor-free three-dimensional localization (CATL) and approximate convex decomposition based localization (ACDL). |
