1Measurement precision
If conventional network monitoring tools are used, then basic network traffic monitoring is possible, but detection precision and ease of operation deteriorate in complex wireless environments with numerous devices
Solution Approach 1:
The system segments the complex monitoring task into distinct functional modules: a network monitoring module for capturing packets, a queue module for organizing data by detection templates, and a user interface module for interaction. This segmentation allows each module to specialize in specific detection tasks, improving precision while maintaining ease of operation through modular design.
Solution Approach 2:
The queue module acts as an intermediary between the network monitoring module and the user interface. It receives wireless data packets, applies detection templates to identify devices exhibiting behaviors of interest, and organizes results before presentation to the user. This intermediary layer enhances detection precision through systematic template application while simplifying user interaction by pre-processing and organizing data.
2Loss of information
If comprehensive monitoring of all wireless devices is performed, then complete network visibility is achieved, but device complexity and processing requirements increase
Solution Approach 1:
Instead of monitoring all wireless devices equally, the system applies detection templates to identify and focus on devices exhibiting specific behaviors of interest. The queue module filters packets based on template criteria, processing only relevant data. This partial action approach maintains complete network visibility for targeted devices while reducing overall processing complexity by ignoring irrelevant traffic.
Solution Approach 2:
The system changes the parameter of detection focus from comprehensive device monitoring to behavior-specific monitoring. Detection templates define specific behavioral parameters (behaviors of interest) that devices must exhibit to be detected. This parameter change transforms the monitoring approach from tracking all devices to tracking specific behavioral patterns, reducing complexity while maintaining visibility of relevant devices.
3Reliability
If real-time detection and location of wireless devices is implemented, then network security response time is improved, but processing speed and time consumption increase
Solution Approach 1:
Detection templates are pre-configured with criteria for identifying devices exhibiting behaviors of interest. The queue module applies these pre-defined templates to incoming packets in real-time, eliminating the need for complex analysis during packet processing. This preliminary preparation of detection criteria enables fast real-time detection while maintaining network security reliability.
Solution Approach 2:
The system replaces complex mechanical analysis of each wireless packet with template-based pattern matching. Instead of performing detailed examinations of packet contents, the queue module compares packets against pre-defined detection templates, rapidly identifying devices of interest. This substitution of complex processing with template matching reduces time consumption while maintaining detection reliability.

AI summary
Aspects of the invention provide a process for detecting sources of wireless data packets exhibiting defined behaviour of interest in a wireless network environment, the process comprising the steps of: monitoring the wireless network environment to receive wireless data packets; populating one or more queues of wireless data packets from the received wireless data packets, wherein wireless data packets received are added to the one or more queues dependent on a detection template to detect one or more devices which are sources of one or more of the received wireless data packets, wherein a detection template comprises code defining one or more algorithms applied to the received packets to define the behaviour of interest, extracting device identifier data from the wireless data packets in the queue to identify one or more detected source devices exhibiting said defined behaviour; generating display data carrying information on a signal strength of wireless data packets from the same of the one or more identified, detected source devices, the display data suitable to be displayed at a user interface, wherein the display data is generated dependent so as to be dependent on an orientation of the antenna relative to the one or more identified, detected source devices; and receiving inputs at the user interface indicating a selection of a detection template made at the user interface to allow an operator to select the defined behaviour of interest.
