Wireless Networks

 Provides:

 Software mobility;  Faster communication;  Low structure cost

 Challenges:

 Bandwidth;  limited resources;  frequent disconnections

Wireless Sensor Networks

 sensor nodes characteristics:

 Low capacity of processor,

communication and battery;

 Functions: sensor or routing;  Can have a level of intelligence;  1 J to transmit 1 bit  0.5 J to receive 1 bit  0.8 J to 208 CPU cycles

OSCAR Cluster Computing

 Manages globally and transparently

cluster resources

 Provide some level of security,

availability and tools to easy management of the environment.

 OSCAR consists of a fully integrated

and easy to install software bundle designed for high performance computing cluster.

Proposed Approach

 Why integrate wireless sensor networks and

Clusters?

 Sensors are densely deployed on environments;  There is a high information stream;  Avoid overload the system with so much data;  Store large amount of data;  Provides remote access  OSCAR: a solution to cluster management

Conclusion and Future Work

In this article we have presented a middleware that was designed and implemented to improve the processing characteristic of a wireless sensor network through the use of the OSCAR software environment.

33

Conclusion and Future Work

Our prototype considered:

  • a number of motes to sensor a field in a real time;
  • data are sent to a base station that will send the data

to a OSCAR Cluster;

  • after a processing time the middleware notifies online a

mobile device.

Conclusion and Future Work

Challenges to be solved as a near future are:

  • Test the implementation for some routing topologies of sensors;
  • Enhance the alerts for different kinds of mobile devices;
  • Make available the final version of the middleware for the

Oscar Group.
