One of the key challenges in wireless sensor networks (WSN) is to save
energy at motes. One method to save battery is radio duty cycling (DC),
which keeps the radio turned off in most of the time and turns the radio on
for a short time to verify if any there are any messages. DC is frequently used
in monitoring applications where only one message is transmitted after the
mote reads its sensor. Usually the mote reads its sensor only once every few
minutes, so few unicast messages are transmitted in the network per time
unit. This work analyzes the use of the DC method in code dissemination.
In this context, multiple broadcast messages are transmitted in a short time.
We examined two specific dissemination algorithms, one of them proposed
for a virtual machine environment, in which the disseminated code is a small
script, and a second one originally proposed for disseminating the code of
an entire application, typically much larger than a script. The objective of
this study is to evaluate the impact of DC on latency and how much energy
was saved when compared to leaving the radio on all the time, which is how
both algorithms work in their original form.
