Energy-bounded reliability modeling for wireless sensor networks

The wireless sensor network (WSN) system is a kind of system in which the consumer energy of a task is strictly bounded. This paper proposed a model of the system and a model of the task which consider energy consume based on task, introduced the energy factor function, and also established a reliability model of WSN based on task. Finally, an illustration of modeling of representative hierarchical cluster topology in WSN was also presented. This method suggested that the method studied has a directive influence to both task division and topology selection of WSN system.
