“…ISSMCRP calculates the detection level function for available channels and selects nodes with strong detection capability, high remaining energy, and large number of neighbors as CHs. EBUCRP 27 derives the optimal cluster radius probabilistically to minimize network energy consumption and equalize the residual energy levels of nodes. Nodes with high residual energy, numerous available idle channels, and low communication energy consumption with neighboring nodes are selected as CHs.…”

“…Additionally, while maintaining the same network radius, we increased the number of CRSNs nodes from 450 to 900 to explore the impact of node density on the performance of ES-ISSMCRP protocol, i.e., the node density has doubled compared to its original value. The additional parameters for the simulation are detailed in Table 2 8 , 15 , 22 , 26 , 27 , 38 , 39 .…”

Existing clustering routing protocols for multi-hop energy harvesting-cognitive radio sensor networks (EH-CRSNs) generally assume perfect spectrum sensing, which is not aligned with the practical spectrum sensing capabilities of nodes in real networks. Additionally, the severe imbalance in residual energy among cluster heads (CHs) negatively affects the successful data delivery. To resolve these problems, this paper introduces a simultaneous wireless information and power transfer (SWIPT)- and imperfect spectrum sensing-based multi-hop clustering routing protocol (ES-ISSMCRP). ES-ISSMCRP makes full use of downlink EH and intra-cluster SWIPT technologies to replenish and equalize the remaining energy among nodes, further extending network lifespan while maintaining network surveillance capabilities. Specifically, to reduce the adverse impact of imperfect spectrum sensing on network performance and improve energy utilization, this paper proposes an EH-based energy level function and associated selection criteria for CHs and relays, facilitating distributed cluster formation and multi-hop routing selection between clusters. To equalize the residual energy among nodes within a cluster, ES-ISSMCRP protocol enables cluster members (CMs) to decide whether employ SWIPT technology with a power splitting (PS) receiver architecture to transmit energy to their CH while sending data. The actual energy value transmitted by CMs using SWIPT technology is deduced by calculating the PS ratio and the expected energy expenditure of nodes for data transmission. Simulation results show that ES-ISSMCRP protocol offers significant improvements over other comparative protocols in terms of extending network lifespan and enhancing network surveillance capabilities.
