The broadcast nature of communication in transmission media has driven the rise of network coding's popularity in wireless networks. Numerous benefits arise from employing network coding in multihop wireless networks, including enhanced throughput, reduced energy consumption, and decreased end-toend delay. These advantages are a direct outcome of the minimized transmission count. This paper introduces a comprehensive framework to employ network coding in these networks. It refines decision-making at coding and decoding nodes simultaneously. The coding-nodes employ optimal stopping theory to find optimal moments for packet transmission. Meanwhile, the decoding-nodes dynamically decide, through SMDP (Semi Markov Decision Process) problem formulation, whether to conserve energy by deactivating radio units or to stay active for improved coding by overhearing packets. The proposed framework, named ENCODE, enables nodes to learn how and when to use network coding over time. Simulation results compare its performance with existing approaches. Our simulation results shed new light on when and how to use network coding in wireless multi-hop networks more effectively.INDEX TERMS Wireless multi-hop networks, Network coding theory, Coding gain, Optimal stopping theory, semi-Markov decision process.

Since low-power Wi-Fi sensors are connected to the Internet, effective radio spectrum use is crucial for developing an efficient Medium Access Control (MAC) protocol for Wi-Fi sensor networks. A connectivity-based multipolling mechanism was employed for Access Points to grant uplink transmission opportunities to Wi-Fi nodes with a reduced number of multipolling frame transmissions. The existing connectivity-based multipolling mechanism in IEEE 802.11 wireless LANs with many nodes may require excessive time to derive the optimal number of serially connected sequences due to the backtracking algorithm based on the Traveling Salesman Problem model. This limitation hinders the real-time implementation of the connectivity-based multipolling mechanism in Wi-Fi sensor networks. In this study, an efficient node insertion algorithm is proposed, by which the number of derived serially connected multipolling sequences that cover nodes in Wi-Fi sensor networks converges to only one as the number of Wi-Fi sensors increases in Wi-Fi sensor networks. As verified by simulation experiments for Wi-Fi sensor networks, the proposed node insertion algorithm produces a near-optimal number of multipolling sequences that cover the nodes in Wi-Fi sensor networks. This study proposes a node insertion algorithm for the real-time implementation of the connectivity-based multipolling mechanism in MAC protocol for Wi-Fi sensor networks.

Recently, full-duplex radio has attracted attention as a solution for wireless local area networks (WLANs) where traffic is exploding but available frequency bands are insufficient. Full-duplex radio exploits various self-interference cancellation technologies to transmit and receive signals concurrently in the same frequency band. Thus, the efficiency of the frequency band is doubled compared with that of conventional half-duplex radios. However, to effectively exploit full-duplex radio, new problems that do not exist in conventional half-duplex radio, such as fullduplex link setup, inter-node interference avoidance, and idle uplink period (IUP), must be addressed. We propose a full-duplex medium access control (MAC) protocol to effectively exploit fullduplex radio by addressing these problems. In particular, our MAC protocol uses an IUP to transmit an acknowledgment (ACK) frame and report the buffer information of nodes. Accordingly, an access point can gather the node's buffer information during the IUP and schedule the transmission of nodes without competition. In addition, because the uplink ACK frame is transmitted during the IUP, additional channel usage time for the uplink ACK frame transmission is not required. Therefore, the proposed MAC protocol improves the WLAN throughput by reducing the number of control frame transmissions and the IUP. The results of our performance analysis and simulation show that the MAC protocol achieves throughput improvements compared with those of previous studies.
