Establishing Mobile Ad-Hoc Networks in 802.11 Infrastructure Mode
... The 802.11 ad-hoc mode is supported by every IEEE 802.11compliant wireless device. Due to this widespread availability, the ad-hoc mode appears especially suited to set up mobile ad-hoc networks (MANETs) between a wide range of heterogenous devices. Yet, in practice, creating a MANET is challenging ...
