Single hopping is implemented by using software approach over IEEE802.11WLAN card using orthogonality concept and protocol. Most feature of single hopping is to achieve virtual Wi-Fi network. Design parameters of this approach are time delay and energy consumption .There are many scenarios where a wireless device connect to virtual Wi-Fi network. In this paper, the authors improve the energy consumption and reduce the switching delay over popular IEEE 802.11 WLAN and present the performance of virtual Wi-Fi for single hop ad hoc network in terms of delay and energy consumption. Finally they approached multi-hopping in an ad hoc network using channelization with node synchronization.
