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.

Low Power, Low Delay: Opportunistic Routing meets Duty Cycling [PDF]
, 2012 Traditionally, routing in wireless sensor networks consists of two steps: First, the routing protocol selects a next hop, and, second, the MAC protocol waits for the intended destination to wake up and receive the data. This design makes it difficult

Spatial duty cycle model for Cognitive Radio [PDF]
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010 Spectrum occupancy modeling in the context of Dynamic Spectrum Access/Cognitive Radio (DSA/CR) constitutes a rather unexplored research area that still requires much more effort. This paper addresses the problem of modeling spectrum occupancy in the spatial domain by proposing a novel theoretical approach that enables modeling the occupancy level ...
