Abstract

A wireless sensor network defined the efficient wakeup scheduling schemes for energy constrained sensor nodes that adhere to the bidirectional end-to-end delay constraints posed by such applications and actuating applications require immediate notification of rare but urgent events and also fast delivery of time sensitive actuation commands. We want to focus on wakeup scheduling in WSN schemes and obtained their study in Asynchronous Wakeup Scheduling, Heterogeneous Wake-up Scheduling, TDMA- Protocol-Scheduling, and Quorum-Based Wakeup Scheduling. All the wakeup scheduling patterns such as synchronized (SMAC) and staggered patterns (DMAC) are considered and we also introduced new efficient wakeup patterns such as crossed-ladders pattern which outperforms other methods. We can show that our proposed techniques significantly improve the performance and allow for much longer network lifetime while satisfying the latency constraints.
