Energy Efficient with Network Coding Multipath Routing Algorithm in Wireless Sensor Networks
Chao Gui,Hua Chen,Baolin Sun,Ying Song 보안공학연구지원센터 2014 International Journal of Future Generation Communi Vol.7 No.6
Network coding is a new paradigm in data transport and promises to change many aspects of wireless sensor network (WSN). Thanks to the recently developed network coding techniques, a high-throughput low-complexity hierarchical protocol can be facilitated due to the multiple-source relay-based data transmissions built on the network coding schemes, especially for the data communications between the source node and destination node. In this paper, we propose an Energy efficient that carefully couples Network coding and Multipath routing algorithm in Wireless Sensor Networks (ENM-WSN). Through an analytical study, we provide guidance on how to choose parameters in our scheme and demonstrate that the scheme is efficient in both multipath and energy consumption. We also present an algorithm for deciding the network coding scheme for a node to further reduce energy consumption by minimizing redundant packet transmissions. Simulation results show that, with the proposed energy efficient with network coding in WSN multipath routing protocol (ENM-WSN), energy consumption, packet delivery ratio, and network lifetime can be improved in most of cases. It is an available approach to multipath routing decision.

An Energy Entropy-Based Minimum Power Cost Multipath Routing in MANET
Baolin Sun,Muyao Lu,Kun Xiao,Ying Song,Chao Gui 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.2
Mobile Ad hoc Networks (MANETs) are non-infrastructure networks consisting of mobile nodes. Since the mobile nodes have limited battery power, they are very important to using energy efficiently in MANETs. In order to maximize the lifetime of MANET, traffic should be sent via a route that can avoid nodes with low energy while minimizing the total transmission power. This paper proposes an Energy Entropy-based minimum Power cost Multipath routing algorithm in MANET (EEPMM). It is typically proposed to increase the reliability of data transmission or to provide load balancing. In simulation experiments, we compare EEPMM routing protocol with SHM and MEA-DSR routing protocol, in terms of the network lifetime, and the energy consumption when a packet is transmitted. The performance results indicate that the proposed scheme is quite adaptive for energy-efficient communication in MANETs.

Network Coding-based Maximum Lifetime Algorithm for Sliding Window in WSNs
( Baolin Sun ),( Chao Gui ),( Ying Song ),( Hua Chen ) 한국인터넷정보학회 2019 KSII Transactions on Internet and Information Syst Vol.13 No.3
Network coding (NC) is a promising technology that can improve available bandwidth and packet throughput in wireless sensor networks (WSNs). Sliding window is an improved technology of NC, which is a supplement of TCP/IP technology and can improve data throughput and network lifetime on WSNs. This paper proposes a network coding-based maximum lifetime algorithm for sliding window in WSNs (NC-MLSW) which improves the throughput and network lifetime in WSN. The packets on the source node are sent on the WSNs. The intermediate node encodes the received original packet and forwards the newly encoded packet to the next node. Finally, the destination node decodes the received encoded data packet and recovers the original packet. The performance of the NC-MLSWalgorithm is studied using NS2 simulation software and the network packet throughput, network lifetime and data packet loss rate were evaluated. The simulations experiment results show that the NC-MLSW algorithm can obviously improve the network packet throughput and network lifetime.

The influence of the atmospheric radon background on the airborne gamma spectrum can seriously affect researchers’ judgement of ground radiation information. However, due to load and endurance, unmanned aerial vehicle (UAV)-borne gamma-ray spectrometry is difficulty installing upward-looking detectors to monitor atmospheric radon background. In this paper, an advanced spectral-ratio method was used to correct the atmospheric radon background for a UAV-borne gamma-ray spectrometry in Inner Mongolia, China. By correcting atmospheric radon background, the ratio of the average count rate of U window in the anomalous radon zone (S5) to that in other survey zone decreased from 1.91 to 1.03, and the average uranium content in S5 decreased from 4.65 mg/kg to 3.37 mg/kg. The results show that the advanced spectral-ratio method efficiently eliminated the influence of the atmospheric radon background on the UAV-borne gamma-ray spectrometry to accurately obtain ground radiation information in uranium exploration. It can also be used for uranium tailings monitoring, and environmental radiation background surveys

Bone Morphogenetic Protein 9 Overexpression Reduces Osteosarcoma Cell Migration and Invasion
Zilan Lv,Ya-guang Weng,Dandan Yang,Jie Li,Min Hu,Min Luo,Xiaoqin Zhan,Peipei Song,Chen Liu,Huili Bai,Baolin Li,Yang Yang,Yingying Chen,Qiong Shi 한국분자세포생물학회 2013 Molecules and cells Vol.36 No.2
Transforming growth factor- (TGF-) is known to pro-mote tumor migration and invasion. Bone morphogenetic proteins (BMPs) are members of the TGF- family expressed in a variety of human carcinoma cell lines. The role of bone morphogenetic protein 9 (BMP9), the most powerful osteogenic factor, in osteosarcoma (OS) progression has not been fully clarified. The expression of BMP9 and its receptors in OS cell lines was analyzed by RT-PCR. We found that BMP9 and its receptors were expressed in OS cell lines. We further investigated the influence of BMP9 on the biological behaviors of OS cells. BMP9 overexpression in the OS cell lines 143B and MG63 inhibited in vitro cell migration and invasion. We further investigated the ex-pression of a panel of cancer-related genes and found that BMP9 overexpression increased the phosphorylation of Smad1/5/8 proteins, increased the expression of ID1, and reduced the expression and activity of matrix metalloproteinase 9 (MMP9) in OS cells. BMP9 silencing induced the opposite effects. We also found that BMP9 may not affect the chemokine (C-X-C motif) ligand 12 (CXCL12)/C-X-C chemokine receptor type 4 (CXCR4) axis to regulate the invasiveness and metastatic capacity of OS cells. Interestingly, CXCR4 was expressed in both 143B and MG63 cells, while CXCL12 was only detected in MG63 cells. Taken together, we hypothesize that BMP9 inhibits the migration and invasiveness of OS cells through a Smad-dependent pathway by downregulating the expression and activity of MMP9.
