| Abstract | |
Wireless Underground Sensor Networks (WUSNs) are complex systems comprised of subterranean sensors interconnected through wireless communication technologies. These networks fulfill a crucial role in monitoring subsurface environments. However, they grapple with a formidable challenge concerning their Network Lifetime (NL), which can be defined as the maximum duration over which the network remains operational and thus connected to a designated observation area. Given the paramount significance of prolonging NL to ensure comprehensive coverage of the observed region, the deployment of wireless power transfer stands out as a preeminent solution for augmenting NL. Nonetheless, the existing sleep-wakeup protocols have not been originally engineered to support this paradigm, which has subsequently resulted in suboptimal network performance. Therefore, we present a study to introduce a novel sleep-wakeup protocol explicitly tailored for wireless power transfer in WUSNs with the overarching aim of optimizing the network's operational lifetime called Sleep-Wakeup Power-Transfer Media Access Control (SWPTMAC). The evaluation of SWPTMAC has been conducted through comprehensive simulations leveraging the Castalia simulator. The empirical findings disclosed an average improvement of approximately 24% when contrasted against incumbent protocols in the domain. (AU) | |
