Abstract: A time based simulation that illustrates the relationship between “smart dust” sensors, their
associated flechettes and the command processor as various targets move through the sensor field.
Objects:
Attributes (private member data)
Behaviors (public member functions)

Objects:
Smart Dust: Heat, Motion, Radiation, Acoustic, Pressure
: Types: H, M, R, A, P //sample for constructor instantiation of type, random chars

double x, y; (locations held constant)
double signal_strength; //set by referee each time step

Signal range (inclusive)
0.0 to 1.0
2.0 to 3.0
4.0 to 5.0
6.0 to 7.0
8.0 to 9.0
The range of the number of sensors: 1,000<N<10,000, user input
Two decimal place precision is required of all signals.
All signals are generated as values: (0.0 <= s <= 1.0 ) + and offset of 2, 4, 6, or 8 as
above.
Flechette :
The number of Flechettes = .02*Number of Sensors
Private Member Data:
Double x, y; kept as const
List <dust*> my_list; //populated by the ref once dust and flechettes are placed
Optional:
Data[5][4];
//the output..
File output for command would include
Type of sensors and their min, mean, max, and n (GRAND TOTALS)
Public Functions
Sense(){add to a list of signals as long as there is a input stream}
Send(){to command a string of data below}
Compute the frequency N, max, min, and mean values of each signal type.
//left to discuss
Command: receives a signal from each flechette for each time step. This signal may be zero.
Compute the OVER-ALL frequency N, max, min, and mean values of each signal type.
N = sum of individual flechette n values
Min = smallest min of each type reported by the flechettes
Max, same..
Mean = sum(ni * meani)/N
Controls:
Size of the domain: 0 to 1000, in both x and y;
User Input Signal range for all Smart Dust: initially 25 //will probably change
Initial position for target = (0, y_random) final position = (1000, y_random)
User input of target profile data from file .
Target data file = id, H, M, R, A, P, speed (or one per line, comma or space
delimited are both acceptable)
Time steps are committed in groups of 5, with user controls for quit or 5 more.
The command will display each flechette data packet then compute and display the
smallest min, largest max, mean of flechette means, total N of each sensor type for each
time step.
SPEED OF TARGET determines how many time steps in the simulation
Compute dx and dy of the speed.
PATH DISTANCE (D) = Sqrt ( 10002 + (yinit – yfinal)2)
Dx (speed in x direction) = (speed*1000)/D
Dy(speed in the y direction) = (speed *(yfinal-yinit))/D
After every 5 time steps, the user is given the option to output all current dust and flechette data
Each of the following should be different in GNUPLOT
Dust signal==0
Dust signal > 0
Flechette
GNU output of the stored data is just the 3 color x,y plots of the data above.
