Abstract: An apparatus and a method are operable to enable peer-to-peer communication between a first communication node having a first server application and an associated first client application and a second communication node having a second server application and an associated second client application in a wireless ad hoc network. In one embodiment, the apparatus includes memory including computer program code configured to, with a processor, cause the apparatus to determine an identity and service capability of the second communication node, initiate the first client application on the first communication node, enable the first server application with the first client application on the first communication node to communicate with the second client application via the second server application on the second communication node, and provide a service associated with the first client application and the second client application between the first server application and the second server application.

Abstract: A system and method for spammer host detection from network flow data profiles comprises constructing one or more cluster profiles and detecting spammer hosts. Construction cluster profiles comprises observing network flow data from one or more hosts; for each host, representing the network flow data associated with the host as a multidimensional vector; clustering the vectors of the hosts into the plurality of cluster profiles; annotating each cluster profile using at least one of black lists and white lists; and calculating a confidence in each cluster profile annotation. Detecting spammer hosts comprises observing the network flow data from a new host; representing the network flow data associated with the new host as a multidimensional vector, and placing the new multidimensional vector of the new host into one cluster profile of the one or more cluster profiles.
