• The distance between sub nets is
beyond maximum transmission range;
• Information can not be directly delivered;
Adding mobility in regular sensor networks.
Why adding mobility in regular sensor network?
Goal– Maintain connectivity in disjointed mobile
sensor network– Design a framework for routing protocol– Design autonomous messenger-based
route discovery protocols – Design agent simulation
Methodology– Discrete event system simulation
specification– Autonomous agent system design

Outline
• Mobile sensor networks possess the nature of high dynamical connection and disconnection which is not predicted and predetermined.
• Agent simulation adapts to the nature.• Every autonomous agent corresponds to a
self-configurable, self-adaptable and self-maintainable mobile sensor.
• We designed the agent simulator. It utilized the Discrete Event System Specification (DEVS) and DEVSJAVA which was developed by University of Arizona.
Motivation
Basic Architecture of DMSN Agents
Responsibility of Every Sensor and Target Agent:• Data Structure; • Action Base;• State Transition Machine;• Action Policy;• Messages In/Out;
Responsibility of Every Cluster Coordinator Agent:• Member Management;• Role Management; • Action Management;• Topology Management;
Responsibility:• Register/Deregister Cluster Coordinator Agent;• Coupling Management in DMSN; • Dynamic Simulation Environment Management;
