Abstract
Techniques are provided for determining mobility of a first node in an ad hoc network. A particular node generates a fixed neighbor node table comprising second nodes in the area of the particular node which are not mobile. The particular node can monitor changes between the first node and the second nodes, and then determine if the first node is mobile based on the changes.
Claims18
A method for determining mobility of a first node in an area of an ad hoc network, comprising:
- generating a fixed neighbor node table comprising second nodes in the area which are not mobile;
- monitoring changes between the first node and the second nodes;
- and
- determining if the first node is mobile based on the changes.
A method for assessing the degree of mobility of a particular node in a mobile ad-hoc network, comprising:
- monitoring and recording in a neighbor table of the particular node each fixed neighbor node in an operable range of the particular node;
- and
- quantifying the fixed neighbor nodes in the neighbor table at each time point that a newly-encountered fixed neighbor node is added to neighbor table of the particular node, wherein a quantification of fixed neighbor nodes in the neighbor table greater than a threshold number indicates a lack of mobility of the particular node.
A first node configured to determine whether it is mobile in an ad hoc network, the first node comprising:
- a processor configured to generate a fixed neighbor node table comprising second nodes which are not mobile, monitor changes in the number of second nodes added to the fixed neighbor node table, and determine if the first node is mobile based on the changes in the number of second nodes added to the fixed neighbor node table.
A first node for use in a mobile ad-hoc network, comprising:
- a processor configured to determine fixed neighbor nodes within an operable range of the first node;
- and
- a memory configured to store a list of fixed neighbor nodes in a fixed neighbor node table, and
- wherein the processor is configured to determine a number of fixed neighbor nodes added to the fixed neighbor node table during a time period,
- wherein the processor is configured to determine that the first node is stationary if the number of fixed neighbor nodes added to the fixed neighbor node table during the time period is less than a threshold number.
