Title: ATTACHING A SENSOR TO A WSAN
Abstract:
Methods and arrangements in a WSAN Gateway (15), a WSAN Manager (16) and a WSAN sensor for attaching an additional sensor (39) to a WSAN (12) comprising at least one existing WSAN sensor (33). The additional sensor emits an indication of its private identity after insertion in the WSAN, and the indication is received by the existing sensors in the WSAN and forwarded to the WSAN Gateway, after an eligibility check. Thereafter, the WSAN Gateway sends an authentication request to the WSAN Manager, which computes an authentication vector and transmits to the WSAN Gateway for the authentication of the new sensor.
