Abstract

Duty cycling technique is widely used in sensor networks to save energy. Due to coverage and other requirements, sensor nodes may have asynchronous duty schedules, which bring additional challenges for data collection. Existing approaches suffer from different limitations such as requirement of time synchronization. This paper proposed a crosslayer design, which utilizes multihop information to find shortcuts and reduces the delay in data collection.
