Specifically, ad hoc, single-hop BAN, PAN, and LAN wireless networks are beginning to appear on the market These technologies constitute the building blocks to construct small multi-hop ad hoc networks that extend the range of the ad hoc networks technologies over a few radio hops [16,17] 1.2.1 Body Area Network A Body Area Network is strongly correlated with wearable computers The components of a wearable...

NAV, the value of which becomes equal to the end of the channel busy period Therefore, all stations within the range of at least one of the two stations (receiver and transmitter) know how long the channel will be used for this data transmission (see Fig 1.9) The RTS/CTS mechanism solves the hidden station problem during the transmission of user data In addition, this mechanism can be used to capture the. .. single-hop wireless technologies Specifically, we introduce the concept of Body, Personal, and Local wireless networks, and we discuss their applicative scenarios The second part of the chapter focuses on the emerging networking standards for constructing smallscale ad hoc networks: IEEE 802.11 and Bluetooth The IEEE 802.11 standard is a good platform to implement a single-hop local ad hoc network because of . techniques in ad hoc wireless networks — part I •Routing techniques in ad hoc wireless networks — part II •Applications of ad hoc wireless networks •Power management in ad hoc wireless networks •Connection.
