v7 v8 7 7 [[PageOutline(2-3,Table of Contents,inline)]] 8 8 == Introduction == 9 Irregularities occurred in a wireless sensor network may cause the data aggregation process to fail such that no response is provided by the sensor island. FAIR is a robust and secure data aggregation protocol that ensures continuity of service even in case of attacks and hardware failures. Instead of requiring waiting for a failure free protocol run, FAIR uses a quality of information to indicate how many failures occurred and what quality can be expected from the response of sensor nodes. The response is then sent together with the quality of information to the initiator of the query. By looking at the quality of information and depending on the application scenario, the initiator of query decides whether to use the response of FAIR or to refuse it. The response may refused for example in a critical application if the quality of information is not high enough. Obviously, having continuous service from a sensor island and the knowledge on the quality of data provides a great flexibility in wireless sensor network applications.9 Irregularities occurred in a wireless sensor network may cause the data aggregation process to fail such that no response is provided by the sensor island.

Therefor , you can use ''''''install.X'''''' to program a sensor node with the '''ID = X'''.100 The '''1''' in the '''install.1''' parameter assigns the '''ID = 1''' to the node being programmed. Therefore, you can use ''''''install.X'''''' to program a sensor node with the '''ID = X'''. 101 101 '''Please note that each sensor node in the network must have a unique ID'''.
