Message forwarding strategy with fuzzy mechanism in opportunistic network
Xiang Yu, Zhihong Liu · 2017
Opportunistic network has the characteristics of frequent network partitions and complicated node relationships, which is difficult to be described by the traditional mathematical model. A message forwarding strategy with fuzzy mechanism is proposed in this paper, which evaluates relationship strength of pair nodes by multi-dimensional status parameters in fuzzy controlling theory and selects forwarding nodes by combining perceived networks status and professional experience, which contributes to avoid the blindness of message forwarding. The simulating results show that the proposed strategy can improve message delivery ratio and reduce average transmission latency in the condition of slightly increasing network overhead.
