A Mobile P2P Network Clustering Method Based on Node Mobility Characteristics

Abstract

The invention discloses a mobile P2P (Peer-to-Peer) network clustering method based on a node mobility characteristic; the method comprises the following steps: step S100, distributing a unique overlay network identifier for all nodes in a mobile P2P network; step S200, calculating an own ability value by the nodes; step S300, calculating distances between the nodes and neighbor nodes thereof; step S400, establishing an own friend node list by the nodes; and step S500, according to the mobility characteristic of the nodes, partitioning friend nodes which are adjacent in physical positions and have the same movement characteristic into one cluster, selecting one node with strong ability from each of the clusters as a cluster head node of the cluster and finally forming the cluster with a more stable structure. According to the method disclosed by the invention, the mobility characteristic of the nodes is fully considered, so that the nodes in the clusters can keep the stability to the largest extent, the problem of structure inconsistency of a topological structure of the mobile P2P network is solved, the maintenance overhead of network topology is reduced, and the expandability of the network is improved.

Description

technical field [0001] The invention relates to the technical field of mobile P2P networks, in particular to a mobile P2P network clustering method based on node mobility characteristics. Background technique [0002] In recent years, with the rapid development of wireless communication technology and the continuous improvement and popularization of mobile device performance, mobile users have been able to exchange and process data anytime and anywhere. With the great success of P2P network on Inertnet, mobile P2P network (Mobile Peer-to-Peer Networks, MP2P) which combines wireless communication technology and peer-to-peer computing has also become a current research hotspot. As an emerging mobile data communication method, the mobile P2P network provides a solution for data transmission in a wireless environment without infrastructure support due to its characteristics of decentralization and self-organization. , emergency rescue and disaster relief, and user information s...
