A Comparison Between Neighbour Discovery Protocols in Low Duty-Cycled Wireless Sensor Networks
نویسنده
چکیده
Wireless sensor networks are applied in a wide variety of applications, such as environment monitoring, target tracking and so on. Neighbour discovery process is an important component of wireless sensor network’s access and basic communication. Duty-cycle based wireless sensor networks can save energy, but challenges the process of neighbour discovery. A comparison between neighbour discovery protocols in low duty-cycled wireless sensor networks is made and a classification of discovery protocols is proposed, i.e. random neighbour discovery and deterministic neighbour discovery. In particular, we analyze the deterministic neighbour discovery protocols in detailed. A qualitative comparison incorporating multiple criteria and a quantitative evaluation on energy efficiency are also included. Finally, the author indicates making full use of neighbour discovery protocol in real deployment is the key of future neighbour discovery protocol design. Keywords—Wireless sensor network (WSN), duty cycle, neighbour discovery, asynchronous asymmetric, analysis of protocols

In duty-cycled wireless sensor networks, deployed sensor nodes are usually put to sleep for energy efficiency according to sleep scheduling approaches. Any sleep scheduling scheme with its supporting protocols ensures that data can always be routed from source to sink. In this paper, we investigate a problem of multi-hop broadcast and routing in random sleep scheduling scheme, and propose a nov...

Network throughput and energy conservation are two conflicting important performance metrics for wireless sensor networks. Since these two objectives are in conflict with each other, it is difficult to achieve them simultaneously. In this paper, a joint duty cycle scheduling and energy aware routing approach is proposed based on evolutionary game theory which is called DREG. Making a trade-off ...

It is a new challenge to provide priority-based delivery in low duty-cycled sensor networks where there are not always-awake communication paths and the wireless links are very time-varying and unreliable. In this paper, we propose a Dynamic Routing Algorithm for priority Guarantee(called DRAG) in low duty-cycled sensor networks. Both schemes of dynamic forwarding decision making and priority-b...
