Superframe-based low-energy-consumption media access control method in wireless body area network

The invention discloses a superframe-based low-energy-consumption media access control method in a wireless body area network, mainly solving the problems of high energy consumption and failure in adaption to data heterogeneity of a competitive mechanism of the current protocol in the wireless body area network. The superframe-based low-energy-consumption media access control method comprises the steps of: dividing a superframe into three stages: a WBAN (Wireless Body Area Network) intranet data period, a period of communication between an individual terminal and a public network, and a WBAN reserved alarm period; setting three priority levels including high priority, secondary-high priority and common priority for each node by a coordinator node by means of monitoring abnormal data and calculating cache and time delay of each sensor node in the intranet data period; and allocating different time slot lengths and sequences according to three priorities. Under the condition that that cache and time delay meet the condition that, time delay is fully utilized, and the characteristic of the data heterogeneity in the wireless body area network is better adapted. Due to synchronism of data, without data interaction, all sensor nodes can judge whether to enter into a sleep mode or not just according to the local cache and the emission rate, thus reducing communication loss.

System, method, and computer program for detection of anomalous user network activity based on multiple data sources

The present disclosure relates a system, method, and computer program for detecting anomalous user network activity based on multiple data sources. The system extracts user event data for n days from multiple data sources to create a baseline behavior model that reflects the user's daily volume and type of IT events. In creating the model, the system addresses data heterogeneity in multi-source logs by categorizing raw events into meta events. Thus, baseline behavior model captures the user's daily meta-event pattern and volume of IT meta events over n days. The model is created using a dimension reduction technique. The system detects any anomalous pattern and volume changes in a user's IT behavior on day n by comparing user meta-event activity on day n to the baseline behavior model. A score normalization scheme allows identification of a global threshold to flag current anomalous activity in the user population.
