Research Project / Applications Seminar SYST 798 STATUS REPORT 20 March 2008 Team:Brian Boynton Tom Hare Eric Ho Matt Maier Ali Raza Key Sponsor: Dr. Kuo-Chu Chang

Java: BSF Modeling Effort Significant updates since last report –Model now features Tier 1, 2, and 3 sensors –Movement of Tier 2 Sensors patterned in Grid overlays –Additional parameters and display options added –Cordon, Latency, Hop Count and Coverage are computed and displayed Analyses Planned for the future –Comparison of Algorithms (incorporation of more algorithms) –Latency, Hop Count, Coverage, Reliability, and Use of Power Parameters that affect analyses –Sensor Range –Communications Range –Sense & Communications Time/Power Used –Reliability/ False Positive Rates

Java: The Graphical User Interface (GUI) Graphical Sensor Display with Chicago Map Six Tabs of Input and Simulation Parameters Text and Numerical Results Output GUI represents what a Biological Response DHS Operations Center Might Use

Java: The GUI (cont.) Shows Sensor Coverage and Communications Paths The DHS Ops Center is at the Chicago District 001 Fire Dept.

Java: The GUI (cont.) Here, the ad-hoc communications Ranges have been increased, leading to increased network connectivity “mesh” Also, note the Tier I Point to Point communications links. This models “small world network” communication. Several communications algorithms are available.

Java: GUI (cont.) Tier II Sensors are mobile ad-hoc and conform to city street and road grids. Each type of sensor has it’s own parameters. Tier I are fixed location backbone nodes, and Tier III are stationary Ad-hoc nodes.

Java: How BSF Communications Works Nodes communicate to “neighbors” within their comms footprint Communications are non-connection oriented (unlike TCP for instance) multicast “bursts” Local data aggregation is performed at each node Nodes maintain a data buffer in case they become disconnected from network

Java: Sample Analysis This depicts the fusion results of 100 detected Smallpox cases randomly distributed throughout Chicago District 001 Latency vs. Hop Count is roughly linear, 20 seconds communications window per hop Packet receipt is nonlinear, due to buffering

Java: Sample Analysis (cont.) Initial ConditionsOverall Results

Java: Realism Parameters were chosen based on information provided by Subject Matter Experts (SME) in Biological Sensors today

CPN Model CPN Model is utilized to analyze time in the simulation of Sensor Grid Communications
