Abstract: With the wide use of intelligent mobile terminals,the research of mobile peer-to-peer networks came to be in-depth continuously．Although the classic Gossip algorithm can be applied to data dissemination in mobile peer-to-peer networks,it cannot adapt to the requirement of mobile networks,especially to the adaptability of churn．Therefore,in order to realize the effective transmission of topology control information and to maintain replica consistency of the node resource lists, an improved Gossip algorithm based on the specific topology was presented to update the resource lists of nodes which belong to the same k-clique,by dynamically adjusting data dissemination probability of each neighbor node．Simulation results show that data dissemination efficiency of the proposed algorithm is improved significantly than the classic Gossip algorithm．It achieves the efficiency of flooding data dissemination strategy and ensures the lower network load.

Key words: Mobile peer-to-peer networks,Gossip,Data dissemination
