This document presents a network-centric information scheme for integrating sensor data and services using a messaging network and distributed data store grids. The scheme uses a structured overlay network to exchange and process application-level messages. Sensor data is sent directly to the content-aware messaging network and immediately distributed to data store grids. Publishers can send new content to the network whenever available. The data is then delivered to consumer applications based on their interests. The scheme provides functions like content-based routing and policy mediation between different overlay networks. It allows easy introduction of a sensor network system over existing IP networks.

2. Abstract
• The data-store grids helps to construct and
manage .
Flexible, elastic, secure, sustainable
• It loosely coupled integration of sensor data
and related services.

• Network-Centric Approach
• Loosely Coupled Service Integration
• Messaging Network
• Smart Grid
• Health Care

4. Introduction
• Brief Description of Content: In the present
paper, a network-centric information scheme
is proposed to satisfy the above requirements
for an enterprise including sensor net.
• The proposed scheme uses structured overlay
network.
• This network, hereafter referred to as a
“messaging network” is used to exhange and
process application-level messages.

5. Proposed Scheme using a Content-
Aware Network
• The sensor data are directly to a content-
aware network messaging network.
• Messaging network is constructed as a
structured overlay network over the existing
network.
• The data are immediately sent to distributed
data store grids.

6. Messaging Network
• A publisher merely sends new content to a
content-aware network configured on a
messaging network whenever the new
content becomes available.

7. Data Store Grid for data-service
Integration
• The data are delivered with varying interests
to individual selective consumer applications
in the messaging of the data.
• Content-based summary the proposed
scheme provides the following basic functions
to the sensor network.

8. Integration of overlay Networks with
Policy Mediation
• Content-aware router can realize policy
mediation between different overlay networks.
• We have constructed a experimental networks
and examine the policy mediation between
overlay networks having different policies.

9. Conclusion
• The proposed scheme can be realized by a
structured overlay network over an ordinary
IP network.
• Therefore, it is easy to introduce the proposed
scheme in order to create a sensor network
based system if the individual system is
connected to the legacy IP network.
• The proposed scheme can also be used with
non-IP networks as a virtual overlay network.
