An Improved Algorithm of Wireless Sensor Networks Routing Protocol Based on LEACH
Published 2013-04-01“…One of the most popular research focuses of wireless sensor network is postponing the life cycle of sensor network as well as reducing energy consumption.An efficient clustering routing algorithm based on LEACH(low energy adaptive clustering hierarch)was presented,which is the representative of hierarchy based protocol in wireless sensor network.The residual energy,average energy and maximum energy are considered in this algorithm while electing the cluster header.It can also limit the number of members of each cluster.At the same time,it can produce the first cluster header among the cluster heads which will use the multi-hop mode to balance the load of network.The simulation results show that this improved algorithm can reduce the energy consumption,extend the network life cycle and ensure the load balance of the system.…”

LTE resource-aware dynamic adaptive wireless multimedia streaming system
Published 2021-01-01“…The quality of user experience in adaptive video streaming, to a large extent, depends on the accuracy of the end-to-end bandwidth estimation.However, bandwidth estimation is very challenging in highly dynamic LTE network.LTE resource-aware dynamic adaptive wireless multimedia streaming system was designed and implemented in which the LTE resource block monitor module keeps monitoring the cell-wide physical layer resource utility.The rate scaling mechanism mapped the throughput to an estimation of available bandwidth and the rate adaption algorithm selected the most appropriate representation combining current available bandwidth with buffer state and played a trade-off between video quality and the risk of stalling.The experimental results on the prototype system show that comparing with the two baseline algorithms, the proposed system achieves the highest average video bitrate while maintaining a fairly low stalling rate, and effectively enhances the quality of experience.…”

A Resource Allocation Algorithm Based on Subcarrier Pairing in Multi-User Cooperative Relay Communication
Published 2014-06-01“…For the power minimization problem in multi-user cooperative relay communications,a resource allocation algorithm based on joint subcarrier pairing and assignment was proposed.Firstly,according to the average channel gain and the target rates of user,the assignment of subcarrier numbers was addressed.Then,in order to choose the subcarrier with best channel condition,a multi-user iterative algorithm for joint subcarrier pairing and assignment was proposed,which could achieve the subcarrier pairing in the cooperative transmissions and virtual pairing in the direct transmission,respectively.Finally,the power allocation was conducted by the water-filling algorithm,so that each user could use the minimum power for transmission.The simulation results indicate that the proposed algorithm can conduct subcarrier pairing and assignment effectively to minimize the total transmission power while meeting the users' target rate requirement.…”

Algorithm based on randomly assigning filters to reduce PAPR in GFDM system
Published 2016-09-01“…As an alternative of the fifth generation mobile communication system waveforms,generalized frequency division multiplexing(GFDM)which has more advantages over OFDM has been trusted into the limelight.Nevertheless,GFDM still suffers from a high peak to average power ratio(PAPR).Considering that different filters have their own phase-frequency characteristics,a new algorithm based on randomly assigning filters to reduce PAPR in GFDM(RAF-GFDM)was proposed.According to the feature of GFDM system that the filter structure could be selected flexibly,different filters were assigned to subcarriers randomly to adjust the phase congruency due to signals superimposition.Additionally,this method can suppress PAPR effectively without causing signal distortion.Theoretical analysis and simulation results demonstrate that the proposed algorithm does not bring additional calculation costs while reducing PAPR and almost has no effect on the bit error rate(BER),and it may provide a higher application value.…”
