Impact of Duty Cycle Variation on WSNs [PDF]
2009 3rd International Conference on New Technologies, Mobility and Security, 2009 Wireless Sensor Networks (WSNs) operate with varying duty cycles to meet their application-specific criteria such as the availability, reliability, and the life expectancy of the system. This variation in duty cycle consequently affects the system characteristics including the interference and collision of signals.
