MAC LAYER PROTOCOLS
MANETs. Dynamically, channels are assigned to the hosts, when
they require them. e bandwidth is divided into a control channel
and multiple data channels, and every node is prepared with two half-
duplex transceivers. For exchanging control packets (using maximum
power), one transceiver operates on the control channel for reserving
the data channel; the other switches between the data channels for
exchanging data and acknowledgments (with power control). When
a host wants a channel to converse with another, it engages itself in
an RTS/CTS/RES switchover, where RES is a special reservation
packet signifying the appropriate data channel to be used.
Every node has a table of power levels for use while communication
goes on ...
