Multi-constraints QoS routing optimization based on improved immune clonal shuffled frog leaping algorithm by Yi LU, Mengying XU, Jie ZHOU

“…Aiming at the multi-constraint routing problem,a mathematical model was designed,and an improved immune clonal shuffled frog leaping algorithm (IICSFLA) was proposed,which combined immune operator with traditional SFLA.Under the constraints of bandwidth,delay,packet loss rate,delay jitter and energy cost,total energy cost from the source node to the terminal node was computed.The proposed algorithm was used to find an optimal route with minimum energy cost.In the simulation,the performance of IICSFLA with adaptive genetic algorithm and adaptive ant colony optimization algorithm was compared.Experimental results show that IICSFLA solves the problem of multi-constraints QoS unicast routing optimization.The proposed algorithm avoids local optimum and effectively reduces energy loss of data on the transmission path in comparison with adaptive genetic algorithm and adaptive ant colony optimization algorithm.…”

Design of automatic routing algorithm based on overlapping hierarchical induction by Jianhong ZHENG, Heyun CHEN, Pengguang ZHOU, Hao XU

“…Aiming at the problem of impulse noise with large amplitude fluctuation and strong time-varying characteristics,which seriously affected the communication performance of power carrier network,the power line network topology and the classical routing algorithm of power line carrier communication were analyzed,and on this basis,an algorithm of overlapping hierarchical induction algorithm (OHIA) was proposed,which proved the feasibility of the algorithm and gave the inductive factor transfer algorithm,route addressing process and forecast based route maintenance strategy.Through the NS-3 simulation platform to establish the PLC model,respectively,ant colony algorithm and overlapping layer induced PLC automatic routing algorithm were simulated.The simulation results show that compared with the ant colony algorithm,the proposed algorithm improves the success rate of the first communication in the strong time-varying channel environment,and makes great progress in the large-scale networking of PLC.…”
