Primary-user behavior based joint routing and channel allocation algorithm in cognitive radio networks by Jing LIU, Pin-yi REN, Shao-li XUE, Chao ZHANG

“…To resolve the unstable routing problem due to the variation of spectrum availability caused by primary users’ behaviors in cognitive radio networks (CRN),a primary-user behavior based joint routing and channel allocation (PUB-JRCA) algorithm was proposed.The PUC-JRCA algorithm characterized the primary-user behavior by using the call-based model.According to the route discovery mechanism in the dynamic source routing protocol,the destination node selected the route which received the least impact from primary-user behaviors after receiving a number of route requests.Then,the destination sent back the route reply packet (RREP) along the selected route,and the channel allocation was performed when the RREP passed each node on this route.Theoretic analyses prove that the expected available transmission time for the packet delivery is inversely proportional to the probability that PU is active.Moreover,the computational complexity of the proposed algorithm is proportional to the number of nodes in the CRN.Simulation results show that the proposed algorithm has higher packet delivery ratio and lower average packet delay than the Gymkhana routing scheme.…”

Interspecific and Intersexual Differences in the Chemical Composition of Floral Scent in Glochidion Species (Phyllanthaceae) in South China by Daihong Huang, Fuchen Shi, Minwei Chai, Ruili Li, Houhun Li

“…Plants of the Glochidion (Phyllanthaceae) genus are pollinated exclusively by host-specific Epicephala (Gracillariidae) moths. Floral scent has been thought to play key role in the obligate pollination mutualism between Glochidion plants and Epicephala moths, but few studies have been reported about chemical variation in floral volatiles of Glochidion species in China. …”

Measurement of dynamic characteristics of a steel-spring floating slab track and a monolithic roadbed track in a subway tunnel by Yongjian Zhou, Guan Xu, Tao Sheng, Hu Jiang, Chao Jin

“…Based on the measured frequency-division vibration levels, vertical and transverse resonant vibrations of the tunnel wall of floating slab track were 15–22 dB smaller than those of monolithic roadbed track. However, low-frequency wheel-rail forces increased vibrations from 1 to 20 hz, which may have a negative influence on soil ground vibrations.…”
