WebWSN devices include a low-rate, short-range wireless radio (10–100 kbps, <100m). While currently quite limited in capability too, these radios are likely to improve in sophistication over time – including improvements in cost, spectral efﬁciency, tun-ability, and immunity to noise, fading, and interference. Radio WebThe seven layers of the ISO OSI reference model ( Fig. 9) are: (1) the physical layer, (2) the data link layer, (3) the network layer, (4) the transport layer, (5) the session layer, (6) the presentation layer, and (7) the application layer. Specific protocols and their description are considered in subsequent sections. Fig. 9.
