Abstract
A device, method, computer program product, and network subsystem are described for determining a node-speed-change-prediction-dependent signal route and routing wireless data along the determined node-speed-change-prediction-dependent signal route.
Claims34
A communication method comprising:
- (a) receiving wireless data to be routed to a destination node;
- (b) determining an initial node-speed-change-prediction-dependent signal route;
- (c) determining a suitability indicator for at least one intermediate node on the initial, node-speed-change-prediction-dependent signal route, including:
- (i) receiving state information about the at least one intermediate node;
- (ii) using the state information and a look-up table, which has speed as an operand, to generate a location-dependent speed model and a vehicle-dependent speed model for the at least one intermediate node;
- and
- (iii) generating the suitability indicator for the at least one intermediate node using the location-dependent speed model and a vehicle-dependent speed model;
- (d) determining a suitability indicator for at least one outside node that is outside the initial node-speed-change-prediction-dependent signal route, including:
- (i) receiving a zone identifier from outside the initial node-speed-change-prediction-dependent signal route;
- (ii) generating a prediction of a node characteristic of the at least one outside node based on the zone identifier;
- and
- (iii) generating the suitability indicator for the at least one outside node based on the prediction of the node characteristic;
- (e) modifying the initial node-speed-change-prediction-dependent signal route to generate a node-speed-change-prediction-dependent signal route, including:
- (i) using the suitability indicator for the at least one intermediate node to exclude an intermediate node from the node-speed-change-prediction-dependent signal route;
- and
- (ii) using the suitability indicator for the at least one outside node to include an outside node on the node-speed-change-prediction-dependent signal route;
- and
- (f) routing the wireless data along the generated node-speed-change-prediction-denendent signal route.
