Primary agent

2 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University Initialization

  • 1. join the smart space
  • 2. insert description triples
  • 3. insert protection for description, output and state triples
  • 4. calculate and inserts initial output and state triples
  • 5. subscribe to input triples

Operation Receive new input triples Calculate new

  • utput and

state triples Update calculated triples

Substitute agent

3 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University Initialization

  • 1. join the smart space
  • 2. insert description triples
  • 3. insert protection for description triples
  • 4. subscribes to triple that indicates what primary agent is

substituted by this one (‘Substitutes’ triple) Operation Receive new input triples Calculate new

  • utput and

state triples Update calculated triples Receive substitution program Subscribe for input triples

Choosing the Substitute Agent

4 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University

Primary Agent

type = calculation

Substitute Agent

type = calculation

Substitute Agent

type = signal_processing

Substitute Agent

type = condition

Motivation

5 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University

  • The behavior and basic operations of the agents are always

the same

  • The agents differs only in their programs

RoDaFlow Framework

6 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University

  • Allows to create dataflow network agents for Smart-M3

platform

  • Allows to create agents by implementing only their programs
  • Created agents support substitution mechanism
  • Written in Java
  • Uses Java KPI

Implementing Primary Agent

7 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University To create primary agent:

  • Implement AgentProgram interface
  • Create instance of PrimaryAgent class
  • Pass implemented agent program to created instance
  • Call the joinSIB method on the PrimaryAgent instance

Implementing Substitute Agent

8 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University To create substitute agent:

  • Implement SubstituteAgentProgram interface
  • Create instance of SubstituteAgent class
  • Pass implemented substitute agent program to created instance
  • Call the joinSIB method on the SubstituteAgent instance

RoDaFlow Framework Benefits

9 Denis Laure Yaroslavl FRUCT Lab P.G. Demidov Yaroslavl State University

  • Saves the agents developer's time
  • Simplifies the development of the agents
  • Hence simplifies the development of dataflow network

based systems

  • Does not require from the developer any additional

knowledge of substitution mechanism implementation

  • Allows to create agents for:
  • Popular desktop platforms
  • Mobile devices
  • Oracle's Internet of Things platform
