Abstract
Current wireless sensor network applications face
challenging power constraints that demand low duty cycles. In
this paper, we propose an energy-efficient, flow-specific medium
access scheme that is capable of achieving low duty cycles while
taking advantage of the performance improvements available
through a flow-specific medium access approach. The scheme is
based on an adaptive sleep and wake cycle that responds to
changes in both contention and non-contention traffic loads
through the use of preamble sampling. A preamble sampling
probability parameter is introduced to manage the trade-off
between energy efficiency and network throughput and delay
performance. A performance analysis is conducted and verified
through simulation.
