this character we will explain terminology according to IEEE802.11 Std.
 Ad-Hoc Network(Peer to Peer)
A network composed solely of stations within mutual communication range of each other via
the WIRELESS medium(WM). An Ad Hoc network is typically created in a spontaneous
manner. The principal distinguishing characteristic of an ad hoc network is limited temporal
and spatial extent. These limitations allow the act of creating and dissolving the ad hoc
network to be sufficiently straightforward and convenient so as to be achievable by
nontechnical users of the network facilities; i.e., no specialized “technical skills” are required
and little or no investment of time or additional resources is required beyond the stations that
are to participate in the ad hoc network. The term ad hoc is often used as slang to refer to an
independent basic service set(IBSS).
 Infrastructure Network
The infrastructure includes the distribution system medium (DSM), access point(AP), and
portal entities. It is also the logical location of distribution and integration service functions of
an extended service set(ESS). An infrastructure contains one or more APs and zero or more
portals in addition to the distribution system(DS).

 Station service(SS)
