Abstract
A method and apparatus for deduplication of sensor data is described. In one embodiment, a method includes receiving a plurality of sensor packets P at a network gateway apparatus. Each packet Pi has a corresponding timestamp Ti. The method includes storing a subset of the plurality of received packets P' for a first period of time T1. The method also includes comparing each of the stored packets P′i to other stored packets P′j to determine an equivalence. In response to determining the equivalence of the stored packet P′i with P′j, the method includes forwarding only one of packet P′i or P′j to a destination.
