| Summary: | In wireless sensor network (WSN), energy efficiency is the most fundamental issue that requires special attention during the design of communication
protocols. Energy waste is largely contributed by collision, idle listening, overhearing
and over-emitting that occur at medium access control layer. One of the most widely
used mechanism energy saving in WSN, specifically at MAC layer is Duty Cycle.
Duty Cycling coordinates the sleep/wake-up time sensor nodes to maximize the network lifetime while achieving specific application goals such as high throughput or
low latency. Most existing works focused more on static duty cycling which cannot
guarantee the desire end-to-end delay at varying network condition. In applications
with specific delay requirement, the duty cycling of every node should be adjusted
separately ay runtime depending on the network conditions to achieve desired delay
guarantees and energy efficiency. Recently, a few adaptive duty cycle schemes were
introduced. Although energy consumption has been reduced by some degree, it leaves
an open ended to the degradation of quality of service. In this research, we find
the optimum data transmission in WSN. We purpose a variant of an adaptive duty
cycle scheme for MAC protocol. By adaptive, these factors determine the duration
of node’s listen period for various packet transmission scenarios and requirements.
This result in less waiting time for each packet to be transferred as well as reduce
the re-transmission of undelivered packets. We anticipate this proposed method will
improve the energy consumption and QoS of each node and thus the WSN. The
success of this project will be contributed to the performance improvement and
cost-effective sensing device. |
