Study on multi-channel reservation based MAC protocol for sensor networks by ZHANG De-sheng1, LI Jin-bao1, GUO Long-jiang1

“…Aiming at triple hidden terminal problems in wireless sensor networks,an adaptive duty cycle based multi-channel MAC protocol was proposed,called MCR.MCR efficiently handled triple hidden terminal problems with multiple channel reservation.By minimizing the lower bound of average times of channel switching in MCR,the optimal duty cycle in theoretical analysis was obtained.To investigate values of multiple channel reservation and dynamic duty cycling in MCR,extensive simulation and real testbed experiments were conducted.The results show that compared with other protocols,when the number of channels is larger or loads are heavy,M-cube improves throughput and energy effi-ciency significantly.…”

Understanding the resident group by Ruth Emond

“…The low morale of residential workers and their sense of isolation from child care policy and practice developments have been well documented (Berridge & Brodie, 1998, Murray & Hill, 1991). Over recent times there has been a move to raise the profile of such practitioners and to identify the complex and skilled role that they perform in the lives of the young people in their care. …”

Analysis of the Mechanics Characteristic and Virtual Prototype of Water-cooled Gearbox in Bell-less Top of Blast Furnace by Xu Mingtao, Liu Fengwei, Zheng Xue, Lu Xianzhong, Chen Manyi

“…The water-cooled gearbox is the key component of bell-less blast furnace top.Its function is to drive and control the rotation and tilt of the material distribution chute to meet the requirements of different material distribution.BY using the virtual prototype technology,taking the water-cooled gearbox of blast furnace as research object and the research of its dynamics simulation is carried out.The simulation results show,either in high or low speed rotation,the meshing force of the outer ring gear is comparatively small.Contrarily,when in tilt,the meshing force of the outer ring gear is comparatively large,the maximum meshing force is nearly 2times of the former,it is show that the distributing device is not very stable when the chute tilting.…”

Blockchain-based ARP defense scheme by Fanming LIU, Wei SHI

“…In order to improve the difficulty of maintaining the static binding method when defending against ARP attacks,a defense method was designed with the features of low cost of defense and easy maintenance by using the idea of a blockchain technology.The blockchain structure had been improved,and the transaction index table structure had been designed to identify attacks and update data in a timely manner to prevent subsequent attacks.The content of the transaction index table was updated after the IP address was changed normally to ensure the correctness of the query.Analysis and experiments show that the blockchain-based defense method has the following merits:high security,guaranteeing the data is not tampered with,low cost of maintenance,and effective prevention against ARP spoofing attacks.…”

Tracing IP-spoofed packets in software defined network by Songjie WEI, Xin SUN, Rudong ZHAO, Chao WU

“…IP packets back tracing is to find the source host hop by hop from the destination.The method found the forwarding path of target packets and source host by adding probe entry into flow tables on SDN switches and analyzing the effective back tracing Packet-in messages sent by related switches.The proposed scheme can provide convenience for debugging network problems ,so that the network administrator can obtain the forwarding paths of any data packets.Furthermore,it can help to solve the problem of IP spoofing.Experimental results prove that the traceability method can find the forwarding paths of target packets in a timely and accurate manner without affecting other traffic or significant system overhead.…”

Chinese IP-level network topology measurement and analysis by ZHANG Yu, FANG Bin-xing, ZHANG Hong-li

“…To build the prospect of Chinese IP-level topology,the traditional destination sampling method was evaluated;three new improved techniques were developed;and Chinese network was measured.With the methodology of complex network,the topology characteristics were extracted and compared.The sizes of autonomous systems（AS） were investi-gated with the IP2AS technique.The results showe that lots of information is missed by the traditional method;the load is reduced to about a half by the new techniques while the completeness is retained;and the size of new discovered Chinese topology is 5 times as many as that discovered by CAIDA’s skitter.Compared to skitter’s topology,the more complete topology showe more observable dissortativity,weaker clustering,shorter distance and more disequilibrium of node traf-fic distribution.The heavy-tailed distribution of AS sizes is discovered.…”
