For improving throughput and energy efficiency in wireless sensor networks, multi-channel media access control has been proposed. Existing multi-channel MAC protocols are mainly focus on channel assignment and media access, it means that a senor node is bound with one channel, which makes the whole network inflexible and cannot be adapted to the variations of environment. In this paper, we proposed...
Time synchronization and energy saving are important for sleeping-based media access control protocols in wireless sensor networks. Existing time synchronization methods were not designed for energy-efficient and sleeping based MAC protocol in WSN in mind. We proposed the energy-efficient clustering time synchronization algorithm by introduce synchronization schedule adopting and border node controlling...
