These networks are used to monitor physical or environmental conditions like sound, pressure, temperature, and co-operatively pass data through the network to the main location as shown in the figure. Theoretically, your WSN is a wireless network that consists of base stations and numbers of nodes (wireless sensors). Dense networks are not only large-scale networks… Wireless is convenient and less expensive Limitations and political and technical difficulties inhibit wireless technologies Lack of an industry-wide standard Device limitations oE.g., small LCD on a mobile telephone can only displaying a few lines of text oE.g., browsers of most mobile wireless devices wireless environment that uses the 802.11 or WAP standards. Large networks are built by applying routing between nodes. Wireless communication is difficult because you more or less have to have a background in radio communication to understand radio based wireless networks.
