IntroductionNodes in an ad hoc network share a

common broadcast radio channelAccess to this shared medium should be

controlled in such a manner that all nodes receive a fair share of bandwidth.

Characteristics of wireless medium is completely different from those of wired medium

Ad Hoc Networks have to address node mobility, limited band width availability, error-prone broadcast channel, hidden and exposed terminal problems and power constraints.
