We propose in this work a cooperative digital investigation scheme in wireless sensor networks. We describe a multi layered architecture of a WSN that can support the com plexity of the developed investigation-basedalgorithms and mechanisms. A set of techniques are proposed to: a) trans parently monitor communication, and securely collect and forward evidence; b) aggregate and analyze them to deter mine the identities of nodes that were involved with for warding the alerts; and c) identify some potential attack scenarios that may have targeted the WSN.
