Abstract

Availability of medium protocol rules make access to such networks that are shared to be accessed in an orderly manner. This allows all involved to share into a limited wireless bandwidth. Wireless channels have their own issues including carrier sensing, which depends on location, time among other issues. This article addresses the problems associated with scheduled access by delving deep and looking at such issues as energy consumption and MAC protocols output in wireless sensor networks. This article therefore analyzes MAC protocols specially developed for use in sensor networks. It is worth pointing out that MAC protocols are different from both scheduled and unscheduled protocols.
