Study on Key Technologies of MANET

As MANET has characteristics like multi-hop wireless connection, dynamic topology, and limited bandwidth, its routing protocol faces great challenges. This paper briefly introduces the concept and characteristics of MANET. It puts an emphasis on the key technologies (wireless resource management technology, space interface theory technology, routing technology, Internet access technology, address automatic allocation technology, domain name system and service quality insurance technology) of MANET; at the same time, it makes a brief analysis on the realization of wireless resource management, space interface theory technology and service quality insurance technology.
