This paper presents an adjustable sleep scheduling framework for a variety of application in wireless sensor networks (WSNs) so that the lifetime of the network could be prolonged. Varies of typical applications in WSNs are analyzed to identify the same characteristics with which unified interfaces can be designed for all applications, and to identify different characteristics for which interfaces are reserved. This framework can meet the needs of varies applications by simple configuration and adjust itself according to real-time aspects. It can also avoid wasteful duplication, improve work efficiency and provide a good solution to the issue of application independent of sleep scheduling in WSNs. The results of experiments have shown the rationality and practicality of this framework and it can be applied to forest fire monitoring, crop water status monitoring, gas meter reading and other fields.
