چکیده
|
Predicting critical nodes of opportunistic sensor network (osn) can help us not only to improve network performance but also to decrease the cost in network maintenance. however,existing ways of predicting critical nodes in static network are not suitable for osn. in this paper,the conceptions of critical nodes,region contribution,and cut-vertex in multiregion osn are defined. we propose an approach to predict critical node for osn,which is based on multiple attribute decision making (madm). it takes rc to present the dependence of regions on ferry nodes. topsis algorithm is employed to find out ferry node with maximum comprehensive contribution,which is a critical node. the experimental results show that,in different scenarios,this approach can predict the critical nodes of osn better. © 2016 qifan chen et al.
