In this paper, the authors are basically calculating statistical traffic pattern for voluntary Mobile Ad-hoc NETworks (MANETs) which are mobile ad-hoc networks, so first they should know the meaning of MANETs mobile ad-hoc networks are wireless networks which gets configured automatically when it is started for e.g. mobile devices which do not need any wires for connection. In previous studies, it has been given that while sending any files from client to server first file is encrypted and then it is forwarded to the router which will distribute the files into packets from where it will again encrypt those files packets then finally server will receive the encrypted packets and it will decrypt those encrypted packets and finally receive the original files which was initially sent by the client.
