Mobile Ad-Hoc Wireless Networks In Medium Access Control Protocol

Abstract

Nodes in an ad hoc wireless network share a common broadcast radio channel. The radio spectrum is limited, the bandwidth available for communication in such networks is also limited. Access to this shared medium should be controlled in such manner that all nodes receive a fair share of the available bandwidth, and that the bandwidth is utilized efficiently. Since the characteristics of the wireless medium are completely different from those of the wired medium ,and since ad hoc wireless networks need to address unique issues such as node mobility, limited bandwidth availability ,error-prone broadcast channel hidden and exposed terminals problems and power constraints that are not applicable to wired networks ,a different set of protocols is required for controlling access to the shared medium in such networks, This paper focuses on media access protocols for ad hoc wireless networks
