Data Aggregation and Privacy for Police Patrols
  With a widespread growth in the potential applications of Wireless Sensor Networks, the need for reliable security mechanisms for them has increased manifold. This paper proposes a scheme, Privacy for Police Patrols (PPP), to provide secure data aggregation that relies on multilevel routing. Privacy factors have been identified and implemented. Aggregates are prepared and the summary of information is gathered and stored in a repository. The above defined approaches are integrated in police patrol applications and preliminary results are obtained.
