Abstract: Wakeup scheduling in wireless sensor networks is generally an effective way to reduce energy consumption caused by radio transceivers. In this thesis, we propose two wakeup schedules for different classes of applications. The first scheme which is called Informative Preamble Sampling (IPS), is based on low power listening approach and save a significant amount of energy in data link layer. In IPS, transmission power control is used to reduce the number of overhearing neighbors as well as the average transmission energy. The second scheme which is called topology control for delay-sensitive applications, TC-DSA, is a cross layer optimization for the event-driven applications. TC-DSA guarantees the full connectivity of the network by scheduling the sensors in a distributed manner using local information. It increases the longevity of the network for a given upper bound on the end-to-end delay.
