Abstract
A method for detecting the status of a mesh node in a wireless mesh network, wherein a gateway is building up a vector over time by combining active detection, passive detection and binary tests on anomaly metrics and wherein the status of the mesh node is regarded as misbehaving when the vector reaches a certain level.
Claims14
A method for detecting the status of a mesh node in a wireless mesh network of one or a plurality of mesh nodes, wherein a gateway is building up a vector over time by combining:
- active detection of the status of a mesh node by accumulating responses to transmitted queries,
- passive detection of the status of a mesh node by monitoring and collecting routing metric values and storing the values in a table, and
- binary tests on anomaly metrics;
- and wherein,
- the status of the mesh node is regarded as misbehaving when the vector reaches a certain level.
A gateway in a wireless mesh network comprising a memory and a processor, wherein the processor is configured for detecting the status of a mesh node in the wireless mesh network, the processor comprising means for:
- active detection of the status of a mesh node by accumulating responses to transmitted queries,
- passive detection of the status of a mesh node by monitoring and collecting routing metric values and storing the values in a table, and
- performing binary tests on anomaly metrics, and wherein the processor is adapted to build up a vector over time by combining the active detection, passive detection and binary tests, and wherein the status of the mesh node is regarded as misbehaving when the vector reaches a certain level.
