Two-way relaying protocol tailored for sensor network by Qing-feng ZHOU, Zhi-zhong DING, Cai-hong KAI

“…A three-time-slot two-way relaying protocol,named as two-way selective decode-and-forward (TW-SDF) protocol,was proposed.This relaying protocol integrates network coding and the selective decode-and-forward method,and was tailored for wireless networks with simple devices,like sensor networks.Compared with the well-known physical-layer network coding protocol,the considered TW-SDF has the merits of full diversity order gain,low encoding and decoding complexity and easy-to-implement.Provided block codes,an upper bound on the block error rate of TW-SDF was derived and proved,which is valid for all hard decoders.Simulation results further verify that the upper bound is remarkably tight if BCH codes are utilized.…”

Bandwidth allocation games based on network selection for video communication by Shu-zhi WEI, Qi ZHU

“…A bandwidth allocation game based on network selection (BAG-NS) was proposed for video communication in heterogeneous wireless networks.Firstly,according to the video characteristics of different users and current network conditions,the algorithm calculated the weights of network factors and selected the optimum network by combining analytic hierarchy process and entropy theory.Secondly,the user’s utility function with payoff and cost was designed,and a distributed iterative algorithm is used to obtain the Nash equilibrium.Then the existence and uniqueness of the Nash equilibrium are proved.Simulation results show that the proposed algorithm enables different users to reasonably distribute in different networks and takes users’ fairness and network congestion control into consideration,which increases the utilization of network resources,reduces the users’ video distortion,and improves the users’ video quality.…”

Research on space focusing virtual coverage based on orthogonal frequency time reversal method by Yifang NIE, Fangwei LI

“…To solve the problem of information leakage and coverage efficiency in ultra-dense wireless network,the orthogonal frequency-time reversal virtual coverage scheme was proposed.At first,different wireless reversal channels with lower correlation were distinguished by orthogonal carries.Next,after time reversal,the space focusing of each target signal was realized around the terminal.Then,theoretical expressions of the signal coverage and the signal-interference-to-noise ratio were derived and proved.Ultimately,the virtual coverage was shaped,meeting the requirements of users.The coverage of unrelated user not belonging to system was reduced.The results show that those unrelated users are difficult to receive the target signal because of virtual coverage.In addition,the system has higher capacity and security rate of reliable transmission without any more power or antennas.…”

Research on secret key generation based on wireless channel characteristics in body area network by Jingjing HUANG

“…Wireless body area network (WBAN) is a human-centered wireless network.With limitations of power and computation capabilities of WBAN, the significant challenge of ensuring security is how to generate a shared key between two entities based on a lightweight symmetric cryptography.To investigate this issue, a secret key generation scheme in ultra-wideband (UWB) WBAN was designed.In this scheme, the difference of multipath relative delay and its average value were chosen as common random source to reduce key mismatch probability.Furthermore, with the aid of relay, secret key generation rate could be increased.Simulation and test results demonstrate that the proposed scheme can achieve a good tradeoff between key match probability and key generation rate.Furthermore, security analysis of the scheme was also provided to validate its feasibility.…”
