Connectivitities and Power Assignment in Wireless Ad Hoc Networks

A wireless ad hoc network is a collection of radio devices (transceivers) located in a geographic region. Each node is equipped with an omnidirectional antenna and has limited transmission power. A communication session is established either through a single-hop radio transmission if the communication parties are close enough, or through relaying by intermediate devices otherwise. For this reason, ad hoc wireless networks are also called multi-hop packet radio networks. Because of the no need for a fixed infrastructure, wireless ad hoc networks can be flexibly deployed at low cost for varying missions such as decision making in the battlefield, emergency disaster relief and environmental monitoring.
