ABSTRACT: Wireless sensor networks are currently
experiencing widespread enthusiasm in the field of research, mainly because of
the great benefits they promise in terms of flexibility, cost, range and
robustness. In addition, such networks find use in a wide variety of
applications, for example in collecting remote data, type of climate
monitoring, seismic activity, or in other areas suchas home automation and
medical. Unfortunately, their disadvantages are up to their promises. Indeed,
the sensor nodes are subjected to high energy consumption constraints due to
their compact size as well as the deployment environment. Frequent replacement
of batteries is excluded in a field that can be difficult to access. Therefore,
the main challenge remains as a result of miniaturization and reduces power
consumption to maximize network lifetime. The objective of this work is to make
a thorough study of the energy consumption in wireless sensor networks. The
study points are addressed at the media access protocol or MAC protocol.
