 \section{Methodology}
 
 The implementation of the concepts of this work will be done as part of \ac{bms}\footnotemark, a monitoring platform for \ac{p2p} botnets described by \citeauthor{bock_poster_2019} in~\cite{bock_poster_2019}.
-\Ac{bms} uses a hybrid active approach of crawlers and sensors (reimplementations of the \ac{p2p} protocol of a botnet, that won't perform malicious actions) to collect live data from active botnets.

 % TODO: reference for page rank
 In an earlier project, I implemented different node ranking algorithms (among others \enquote{PageRank}~\cite{page_pagerank_1998}) to detect sensors and crawlers in a botnet, as described in \citetitle{karuppayah_sensorbuster_2017}.
+Both ranking algorithms use the \(\deg^+\) and \(\deg^-\) to weight the nodes.
+Another way to enumerate candidates for sensors in a \ac{p2p} botnet is to find weakly connected components in the graph.
+Sensors will have few to none outgoing edges, since they don't participate actively in the botnet.
 
 The goal of this work is to complicate detection mechanisms like this for botmasters, by centralizing the coordination of the system's crawlers and sensors, thereby reducing the node's rank for specific graph metrics.
+The changes should allow the current sensors to use the new abstraction with as few changes as possible to the existing code.
 
 The final result should be as general as possible and not depend on any botnet's specific behaviour but it assumes, that every \ac{p2p} botnet has some kind of \enquote{getNeighbourList} method in the protocol, that allows other peers to request a list of active nodes to connect to.

 If it is not possible, to select a specific sensor so that the monitoring activity stays inconspicuous, the coordinator can do a complete shuffle of all nodes between the sensors to restore the wanted graph properties or warn if more sensors are required to stay undetected.
 
+The improved sensor system should allow new sensors to register themselves and their capabilities (\eg{} bandwidth, geolocation, ), so the amount of work can be scaled accordingly between hosts.
+Further work might even consider autoscaling the monitoring activity using some kind of cloudcomputing provider.
+
+To validate the result, the old sensor implementation will be compared to the new system using different graph metrics.
