Significance of Sampling Rate Converters in WSNS

A Wireless Sensor Network (WSN) is a group of specialized transducers with a communications infrastructure for monitoring and recording conditions at diverse locations. A sensor network consists of multiple detection stations called sensor nodes and sampling rate offsets exist between these nodes. As nodes utilize individual clock sources, sampling rate offsets are inevitable and may cause severe performance degradation. Hence Sampling Rate Converter (SRC) becomes very important and integral part of the multi-rate wireless sensor network.
