Embedded node around a DSP core for mobile sensor networks over 802.11 infrastructure

Digital signal processors (DSPs) are very efficient devices to implement algorithms for signal processing and analyzing. Endowing sensorial nodes from a sensor network with such processing cores it could lead to high performance because of the possibility of parallel and distribute processing and thus reducing the quantity of information spread into the network (network load). If such a node uses for communication a mature infrastructure like 802.11 standard, will be obtained a solution for implementing mobile sensor networks with high performance end cost efficient. In the same way of obtaining high performances with low costs we suggest that on the information chain from the physical quantity to the numerical result, the acquisition part to be done by an audio codec. In this way, the entire network may look like a Voice over IP (VoIP) mobile network, yet the information exchanged will not be voice but measures and commands with quality of service (QoS) inherited from VoIP.
