A signal processing method for event detection have been developed with low power, parallel architectures that optimize performance for unique sensor system includements [25]. Signal processing architectures for sensor networks are also provided in [24, 26, 30].<\/p>\n
<p>Implementation of a parallel data paths with shared arithmetic elements enabling high throughput at low clock rate [25] is presented. This method has been used to implement a micro sensor spectrum analyzer for a 200 sample\/s measurement system [25]. A new object-relational data type is introduced termed as GADT (Gaussian ADT). GADT models physical data as gaussian pdfs [28] and shows that existing ..\/index structures can be used as fast access methods for GADT data. it also presents a measuretheoretic model of probabilistic data and evaluate GADT in its light [28].<\/p> <p>A physical layer driven approach to designing protocols and algorithms is proposed [31] first presents a hardware model for the wireless sensor node and then introduces the design of physical layer aware protocols, algorithms, and applications that minimize energy consumption of the system [31]. The approach prescribes methods that can be used at all levels of the hierarchy to take advantage of the underlying hardware [31]. It also shows how to reduce energy consumption of non-ideal hardware through physical layer aware algorithms and protocols [31]. Micro power data converter is discussed in [24]. Digital signal processing systems, weak inversion CMOS RF circuits are also designed in [24]. This RF circuit utilizes low power [24]. Some physical layer principles are presented in [30]. In [27] it is identified the opportunities and challenges for distributed signal processing for sensor networks.<\/p> <h2 class=\"left\">References<\/h2> [24] G. Asada, M. Dong, T. S. Lin, F.
