  A mobile ad hoc network is a wireless network of mobile devices that
communicate with one another without any fixed network infrastructure. Existing
mobile ad hoc networks are either based on IEEE 802.11 a or b standard. Both
standards provide limited bandwidth and therefore are not suitable for
data-intensive applications such as automated video surveillance. Wi-Fi Direct
is a new technology that enables mobile devices to directly communicate with
each other without a wireless access point. Compare to existing technologies it
provides data rates of up to 250 Mbps which is sufficient for several mobile
data-intensive applications. Wi-Fi Direct technology, however, has two main
limitations. It does not support communication between two client devices in a
group and it also does not provide support for multi hop communication. This
paper describes a Wi-Fi Direct based multi hop mobile ad hoc network. More
specifically a routing layer has been developed to support communication
between Wi-Fi Direct devices in a group and multi-hop communication between
devices across a group. The proposed system has been implemented on a group of
four Wi-Fi Direct enabled Samsung mobile devices.
