3. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski What is an Agent? Autonomy: agents operate without the direct intervention of humans or others, and have some kind of control over their actions and internal state. Reactivity: agents perceive their environment, and respond in a timely fashion to changes that occur in it. Pro-activeness: agents do not simply act in response to their environment, they are able to exhibit goal-directed behavior by taking the initiative. Social Ability: agents interact with other agents (and possibly humans) via some kind of agent-communication language Agent is software application that has following characteristics: (Wooldridge & Jennings 1995)

4. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Multi Agent Systems and Mobile Agents " There's no such thing as a single agent system" Slogan of the multiagent community A Multi-Agent System (MAS) is a system designed and implemented as several interacting agents that cooperate, coordinate and/or negotiate. Characteristics of MAS: Each agent has incomplete capabilities. There is no global system control (decentralized data and control). MAS Environments: They are typically without centralized designer (possibly open). Agents in the environment may be self-interested or cooperative. Agents must be able to find each other and must be able to interact. (Jennings et al., 1998)

Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Multi Agent Systems and Mobile Agents (con’t) “Agents capable of transmitting themselves, their program and their state across computer network and recommencing execution at a remote site are known as Mobile Agents ” (Wooldridge, 2001)

6. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Biology-Inspired Computing The concept of introducing ideas from biological systems and organisms into computer science.

7. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski What is Bio-Networking ? Example of Biology Inspired Approach for development of decentralized adaptive network applications. It is both paradigm as well as middleware. The project was developed by Department of Information and Computer Science, University of California, Irvine. Sponsored by : [http://netresearch.ics.uci.edu/bionet/] –National Science Foundation, DARPA, Air Force Office of Scientific Research, Hitachi America, Fujitsu, etc. Motivation: –Challenges faced by future network applications have already been overcome in large scale biological systems. (Wang & Suda, 2000)

8. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Bio-Networking Architecture Cyber Entity (CE) – mobile agent designed to follow biological principles and “live” in the Bionet environment. –Attributes that describe the CE: ID, energy level, parent, etc. –Behaviors: Decision making, reproduce, migrate, relationship, spend energy, etc. Bio-net platform – environment where CE exist, in network device with JVM and Bio-Networking platform software. –Resource control, CE scheduling, System Services, Information Services.

9. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Biological principles in Bio-Networking Emergence –Biology: characteristics of the large scale biological system emerge from a group of interacting biological entities. –Bio-Networking: characteristics of the Bio-Networking applications emerge from multiple interacting CEs. Autonomous actions based on local information and local interactions –Biology: biological entities in large scale biological systems act autonomously. –Bio-Networking: CE are autonomous agents following goal driven behavior. Birth and Death as Expected events –Biology: biological entities are born and die. –Bio-Networking: CE can crash or die, CE can produce another CE

10. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Biological principles in Bio-Networking (con’t) Energy and Adaptation –Biology: biological entities adopt to the environment in order to maximize their energy gain while minimize their energy expenditure –Bio-Networking: Introduces the concept of energy level for each CE. CE acquire and spend energy depending on their actions and interactions. CE without energy dies. Natural Selection and Evolution –Biology: evolution occurs as a result of genetic diversity and natural selection –Bio-Networking: CE combine behavior and parameters when reproducing. Natural selection is based on the energy maximization policy.

11. Bio-Networking: Biology Inspired Approach for Development of Adaptive Network Applications 21 May 2005Ognen Paunovski Future of Global Network Applications must be able to scale to billions of nodes and users must be able to adapt to diverse and dynamic network conditions. must be secure and highly available should require minimal human configuration and management Requirements for future network applications: Scalable – CE can multiply sufficiently to accommodate high service demand or die to reduce the total population number. Adaptive – CE adopts to the environment to maximize energy gain (migration, birth and death, natural selection, evolution). Available – CE can migrate to location best suited to satisfy service demand Survivable – The system maintains minimum population on distributed nodes. There is no central authority, loss of any part of the population can easily be replaced. Bio-Networking properties:
