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.

5
Advantage of Mobile Agents

• Reduce the flow quantity
• Integrate with distributed structure seamlessly
• Pervasive computing

6
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.

7
Structural Model of Network Management

• There are three types of network management
  structural models
• Centralized Single Manager Station.
• Distributed Multiple Manager Stations.
• Hierarchical Different level of Manager
  Stations.

8
Hierarchical Architecture of policy Management

• The three levels of this hierarchical
  architecture are Policy Manager (PM) at the
  highest level, Cluster Policy Agent (CPA), Local
  Policy Agent (LPA).
• An LPA manages a node.
• A CPA can manage multiple LPAs.
• A PM manages multiple CPAs it is also a policy
  agent actually.

9
Mobile Agent-Based Network Management

• A complete node in the network includes agent
  execution environment, policy agent and the real
  managed node.
• The policy information base (PIB) is an ordered
  set representing data types.
• Each agent is kept on standby any time, so the
  real-time performance is improved effectively.
• The common node informs the agent with data to
  the cluster head after received information.

10
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.
