Mobile Agent Based Policy Management for Wireless Sensor Network
[attachment=28563]
Introduction
WSN network management critical problem when a large number of sensor nodes are involved.
In order to simultaneously satisfy limitations like power constraints, limited bandwidth, distributed coordination and deployment we need an efficient network management in WSN.
Mobile Agent-based policy network management system for wireless sensor networks, which aims at providing effective management mechanism.
Mobile Agent Technology
Mobile agent is the combination of distributed and artificial intelligence technologies the main concept of it is to execute in distribution.
Mobile agent is a section of code that can implement user tasks autonomously.
A mobile agent can suspend its execution on a node, and then migrate and transfer its code, data state, to another node on the network.
Thus, it can save the network communication bandwidth effectively, and improve the degree of parallelism and real-time performance of the task execution.
Policy Technology
Policy management is useful in various areas, e.g. Configuration management, Quality of service control , Traffic engineering , etc.
The architectural components of the Policy Framework include a Policy Decision Point (PDP) and Policy Enforcement Points (PEP), and a policy repository.
Network management functionality can be realized by policy agents.
Conclusion
The management system described in this paper shows that a reduction in management traffic overhead can be achievable by mobile agents and policy management.
This architecture reduces the network management requirement for bandwidth, and upgrades the imitativeness, adaptability and re-configurability of network management system.
It has a good practical and research value for geographically distributed network environment.
