Data dissemination policy by using human mobility patterns for opportunistic networks
摘要
Abstract
Aiming at the low dam-dissemination efficiency of opportunistic networks, a novel data dissemination policy based on human mobility patterns (HMP) is proposed. The policy chooses “destination-matching” (DM), “destination-arriving time” (DAT), and “network hops” (NH) as its three key factors in data dissemination, and regards the general evaluation of the three factors as the criterion for selecting relay nodes, and the criterion is used for data forward in opportunistic networks. It reduces efficiently the network tratfic and resource consumption caused by useless data dissemination of multiple hops through the design of selecting relay nodes, and builds the data dissemination model. Also, it analyzes the upper and lower bounds of the data dissemination range. The simulation results show that the new policy improves the network QoS performance and reduces the data end to end delay and network resource consumption.关键词
