“…A protocol that integrates energy-efficient use and QoS support, a problem in Wireless Sensor Networks, has been proposed [12], [18], [19]. The system proposed [18] is an integrated wireless transmission system that combines QoS requirements from the application layer with modulation and transmission schemes in the data link and physical layers. In addition, the protocol proposed here is divided into intracluster and inter-cluster on a cluster basis.…”

In this paper, we propose a MAC protocol that provides energy efficiency and QoS for wireless sensor networks. Because it does not classify the data according to the characteristics, traditional MAC protocols for Wireless Sensor Networks cannot provide service differentiations for different traffic classes. For the purpose of QoS support, the input data to the node is divided into priority classes according to the transmission emergency. Depending on the urgency of the data, the protocol can provide time slots for nodes and take different contention window sizes for different traffic classes. Nodes use the reinforcement learning-based control mechanism to actively infer the status of other nodes to classify effectively under various kinds of traffic conditions. The proposed protocol can meet the QoS requirements of delay-sensitive applications and can effectively deal with the problem of a multi-channel hidden terminal with the use of multi-queue. For the next purpose, the proposed protocol is energy efficient because it is based on sleep mode. To improve the energy efficiency, each node has a short non-overlapping listening interval, saving energy in idle listening intervals. This is one of the ways to efficiently use the energy of a node to extend the life of the entire network. This achieves low power consumption by increasing the throughput of data processed across the network and enabling efficient transmission. The classified data can be further improved by rearranging the data according to the nature of the transmitted data in the queue.

Context‐awareness has recently been considered as a viable performance leverage for adapting protocols to their deployment evolving contexts. In constrained‐based Wireless Sensor Networks (WSN), context‐awareness enables sensors to learn about their contexts and automatically adjust their behaviors to improve the overall system performance. Most of the proposed solutions, however, dealt with the optimization of the usage of resources at the MAC (Medium Access Control) level. In this regard, context‐awareness allows nodes to smartly adapt their behavior to achieve application requirements while maintaining a balanced trade‐off between resources usage and network performances. We first review the most relevant work and proposals exploiting context‐awareness at the MAC level, and then highlight the benefits of using context awareness.
