Proactive self-configuration is indispensable for MANETs like Ubiquitous Sensor Networks (USNs), as component devices of the network are usually exposed to natural or man-made disasters due to the hostile deployment and ad hoc nature of the USNs. Network State Beacons (NSBs) are exchanged among the key nodes of the network for crucial and effective monitoring of the network for steady state operation. The Rate of Beacon Exchange (F E ) and its contents, define the time and nature of the

... e action. Therefore it is very important to optimize these parameters to tune the functional response of the USN. This paper presents a comprehensive model for monitoring and proactively reconfiguring the network by optimizing the F E . The results confirm the improved throughput while maintaining QoS over longer periods of network operation.
