Hybrid Peer-to-Peer search algorithm in all IP broadband mobile networks

To improve the quality of search algorithm in all IP broadband mobile networks, a hybrid Peer-to-Peer (P2P) search algorithm (HPSA) is proposed which is based on the features of P2P technology and all IP broadband mobile networks. Firstly, this algorithm defines parameters to decide the threshold by means of grey relational analysis (GRA); then we put forward an adaptive threshold method to adapt the dynamic environment; finally, it also presents the optimal threshold. The simulations show that HPSA makes a good performance working in all IP broadband mobile networks, the new algorithm improves search quality and mobile users' experience efficiently.
