Synchronization and Performance of a Cooperative Pulse Transmission Algorithm for a Wireless Network of Active Sensors

Free registration required

Executive Summary

A cluster-based, cooperative pulse transmission scheduling algorithm is presented and analyzed for a wireless network of active sensors. Synchronization requirements are defined and addressed to accommodate time, frequency, and phase constraints. Performance metrics for the received Signal to-Noise Ratio (SNR) and the maximum Pulse Repetition Frequency (PRF) are developed and analyzed. A trade-off is found to exist between the two metrics that can be managed by optimizing the number of nodes per cluster. The performance is shown to be substantially better than the conventional "Hand-off' technique and is validated through simulation for both uniform and random arrays.
