Wireless sensor and actor network (WSAN) has received growing interests with the rapid development of Internet of things. Multiple function actors are added into the traditional wireless sensor networks to sense the environment, conduct tasks and give feedback. In this paper, an efficient distributed actor deployment strategy is proposed to address the connectivity maintenance and coverage optimization...
We present a novel cross-layer approach in minimizing energy consumption for multi-hop cooperative sensor networks, under the end-to-end reliability QoS requirement. Taking into consideration the power consumed in receiving and processing circuitry, we jointly determine the optimized routing, relay selection and power allocation strategies for direct transmission, single-relay cooperation and multi-relay...
In this paper, we consider energy-efficient routing for detection in wireless sensor networks (WSNs). Energy-efficient routing for WSNs has been intensely studied recently, but routing for signal detection in WSNs has not attracted much attention. Moreover, we are not aware of any previous work on routing for detection in WSNs that specifically considers the Neyman-Pearson criterion which is the most...
