A method and apparatus in an ad hoc network, comprising: a node advertising a theoretical destination it is not currently connected to as part of a theoretical route; allocating to the theoretical destination a special metric value that gives a reduced likelihood of selection as a suitable route compared to conventionally available routes; determining that a message from a further node is to be transmitted via the theoretical route; the node receiving the message from the further node when the node is at a first location and storing the message; the node moving from the first location to a second location thereby transforming the theoretical route into a new real route; and the node transmitting the message to a second further node as part of the new real route.. . ...

Ad hoc network with unidirectional link

A method and apparatus for use in an ad hoc network, comprising: a node transmitting an extended allowable hold time value to a further node; the node changing its transmission behavior such that the further node stops receiving transmission from the node for an extended period, for example by pausing transmission at least in the direction of the further node; and the further node treating the link to the node as intact during the extended allowable hold time. The transmitting of the extended allowable hold time value may be performed earlier than a next routine transmission of routine allowable hold time value would have been sent. ... Bae Systems Plc

Producing data describing target measurements

Methods and systems for producing data describing target measurements using a processor (102) in a system (100) having at least one on-board sensor (106) on a vehicle. The method includes obtaining data from an on-board sensor (106), obtaining data from a sensor (108) off-board the vehicle, activation approximating (312) a target alignment error between the on-board and off-board sensor data, receiving target alignment error data in respect of at least one other sensor set comprising at least two sensors, estimating (316) a bias using the received target alignment error data and correcting the approximated target alignment error using the bias, and performing (320) a data fusion process on the obtained off-board sensor data and the obtained on-board sensor data using the approximated target alignment error to produce target measurement data.. ...
