Effects of selfishness in the opportunistic network under two different movement models
Tianyu Zheng, Yingbiao Wang, Xuebin Ma · 2016
Analyzing the effect of nodes' selfishness in the opportunistic network is a hot research. In previous studies, people only perform simulation scenarios under simple movement models. In practice, selfish nodes with different movement models will have different effects in the network. So it's necessary to study the effect of selfishness in the opportunistic network under different movement models. In real-life scenarios, the characteristics of the mobile node's movement is random and clustered. So, in this paper, we discuss how the selfishness of nodes affects performance of the opportunistic network with two movement models, the random walk model (RW) and the clustered movement model. With the experiments, we get the conclusion that effects of selfishness in the opportunistic network is related to the movement model.
