School of Information Engineering, Northeast Dianli University, Jilin Jilin 132012, China） mobile P2P network;super-peer;multi-objective optimization;immune clone algorithm Aiming at the problem of super-peer selection in semi-distributed mobile P2 P network,this paper presented a novel super-peer selection approach. It fully considered various kinds of factors which affected the super-peer selection and divided it into profit attributes and cost attributes. It built the super-peer selection optimization model. This paper solved the problem of super-peer selection by immune clone algorithm with the new constraint handling method. The simulation results show that the new approach can effectively reduce the failure rate of super-peer,and improve the query efficiency of mobile P2 P system. The convergence speed of the proposed algorithm is faster than o |
