Main ObjectivesMain Objectives
The main objectives of this project are
Building a low-power, high-speed network of agents capable of processing a proprietary algorithm used to locate each other in the shortest amount of time, and with acceptable accuracy;
Verifying the functionality of the distributed network through simulation and system testing;
Studying the integration of the system onto working prototypes, with specific investigations of the major architectures;
Investigating the use of the agents in a parallel architecture for faster tracking purposes.

System Tasks (1)System Tasks (1)
System Architecture Delineation
Work on the system architecture in order to iron out any of the major design decisions, that would prevent the realization of the on-board ASIC;
Module Selection
Select the different modules that are to be utilized in both components, basing the decision on several factors, such as time, money and complexity;
Tool Selection
Select the tools that are to be used in the design of both the ASIC and the board itself;
System Operation Definition
Define the system operation as will be seen in the prototype;
System Tasks (2)System Tasks (2)
Module/System Simulation (Currently)
Simulate both the modules and the overall system in order to guarantee functional and timing adherence before realization;
Module/System Realization
Implement and integrate the various modules together to realize the entire system;
Verification
Test and verify the various modules. This step is actually done after every module realization or integration, but is grouped here for simplicity;
Prototype Configuration
Build the working prototype and test it to ensure correct functionality

A sample economical decision that has to be made involves the sensors and actuators on the board, and their
interfacing with the ASIC. Refer to figure 2 for a sample decision that has to be made.
Discussion of Discussion of TechniquesTechniques
Currently investigating the use of a radar scheme, a patch antenna scheme or a rectangular sweeping scheme for wireless communication
Came up with a simple geolocational algorithm to measure the distances between the agents
Studying architectural level low-power design techniques such as parallelism and pipelining
Came up with an encryption/decryption scheme in order to correctly identify each agent, filtering out noise and unwanted bounce-back signals
