| 摘 要： | 移动机会网络中,为使用户快速从因特网获取数据,需要选择某些合适节点担任网关。研究了移动机会网络网关选择问题。提出了两种基于节点影响力的网关选择算法:LRGS和CRGS。实验结果证明,两种基于节点影响力的网关选择算法较之随机选择算法均可使性能得到改善;当网络规模较小时,CRGS性能更优;当网络规模较大时,LRGS的性能更优。同时,所提出的两种算法均有较好的可扩展性。

| Abstract: | In mobile opportunistic networks, suitable nodes are needed to be chosen to perform as gateways for users to obtain data from the Internet rapidly. Investigate the problem of gateway selection in mobile opportunistic networks. Propose two gateway selection algorithms based on the influence of nodes: LRGS and CRGS. Experiment results prove that compared with the random selection algorithm both the two algorithms can improve the network performance. When the network size is small, CRGS performs better, and it is big LRGS performs better. Both the two proposed algorithms are scalable |
