The increased adoption of Internet of m.dical Things (Iom.) technologies has resulted in the widespread use ofBody Area Networks (BANs) in m.dical and non-m.dical dom.ins. However, the perform.nce of IEEE 802.15.4-based BANs is im.acted by challenges related to heterogeneous data traffic requirem.nts am.ng nodes, includingcontention during finite backoff periods, association delays, and traffic channel access through clear channelassessm.nt (CCA) algorithm.. These challenges lead to increased packet collisions, queuing delays, retransm.ssions,and the neglect of critical traffic, thereby hindering perform.nce indicators such as throughput, packet deliveryratio, packet drop rate, and packet delay. Therefore, we propose Dynam.c Next Backoff Period and Clear ChannelAssessm.nt (DNBP-CCA) schem.s to address these issues. The DNBP-CCA schem.s leverage a com.ination ofthe Dynam.c Next Backoff Period (DNBP) schem. and the Dynam.c Next Clear Channel Assessm.nt (DNCCA)schem.. The DNBP schem. em.loys a fuzzy Takagi, Sugeno, and Kang (TSK) m.del’s inference system.toquantitatively analyze backoff exponent, channel clearance, collision ratio, and data rate as input param.ters. Onthe other hand, the DNCCA schem. dynam.cally adapts the CCA process based on requested data transm.ssion tothe coordinator, considering input param.ters such as buffer status ratio and acknowledgem.nt ratio. As a result,sim.lations dem.nstrate that our proposed schem.s are better than som. existing representative approaches andenhance data transm.ssion, reduce node collisions, im.rove average throughput, and packet delivery ratio, anddecrease average packet drop rate and packet delay.

Nitrogen(N) fertilizers in agriculture suffer losses by volatilization of N to the air, surface runoff and leaching into the soil, resulting in low N use efficiency(NUE)( 50%) and raising severe environm.ntal pollutions. Controlledrelease nitrogen fertilizers(CRNFs) can control the release of N nutrients to NUE in crop production. Different m.thods were used to develop new ***, different CRNF technologies are still underdeveloped due to inadequate controlling on N releasing tim. and/or unsustainable diffusion. The study on the influences of CRNF processing param.ters on m.crobial conditions are lacking when the CRNFs com.osed of various bio-ingredients such as biochar, com.osts, and biowaste. The com.lexity of processing m.thods, m.terial biodegradability, and other physical properties m.ke current CRNFs of questionable value in agricultural production. This research aim. to develop a novel biochar-com.ost-based controlled-release urea fertilizer(BCRUF) to preserve m.crobial properties carried by the com.ost. The BCRUF was synthesized by pelletizing the 50:50(dry, wt/wt) m.xture of biochar and com.ost. BCRUF was loaded with urea and then spray-coated with polylactic acid(PLA). The releasing tim. of two types of BCRUFs, coated and uncoated with PLA, for 80% of N release in water was up to 6 h at three different tem.eratures(4, 23, and 40 °C), com.ared to conventional urea fertilizer and com.ercial environm.ntally sm.rt N(ESN) fertilizer. The releasing tim. of coated BCRUF for 80% N release in soil was up to 192 h(8 days). Fourier-transform.infrared spectroscopy(FTIR) analysis revealed that no new functional groups were found in the release solution, indicating no new chem.cal hazards generated. The differential scanning calorim.try(DSC)tests also verified that its therm.l stability could be up to 160 °C. The m.crobe populations in the BCRUF pellets were reduced after the pelleting and drying processes in BCRUF fabrication, but a few bacteria can endure in t
