Popis: | 97 In this paper, we discuss the problem of the P2P (peer-to-peer) networks with mobility. The peer’s mobility easily causes topology mismatch between the P2P logical overlay network and physical underlying network. The topology mismatch makes P2P network inefficient. Generally, the P2P networks can be categorized as the structured P2P network and the unstructured P2P network. It is suitable for unstructured P2P network developing in the wireless environment because it doesn’t need to maintain a specific structure. But the using of flooding search method will run down the network bandwidth and the mobile handset’s limited hardware. Therefore, in the mobile P2P network, first, we design a new linking rule to decrease the amount of query messages forwarded but still keep P2P network connective. Second, for the mobility of peers, we give a moving rule. Third, by resource information exchanging between the inside neighbors (in the same AP group), the hit rate will increase. Then we estimate the amount of query messages forwarded and hit rate to prove that our mechanism achieves the goal. Finally, we describe the conclusion and future works of our research. |
