报告题目:Approximation Algorithm for the Construction of Fault-Tolerant Virtual Backbone of Wireless Sensor Network

报告时间:93号,1500-1600

报告地点:腾讯会议 ID866 619 476

报告摘要:Approximation algorithm deals with NP-hard problems by providing theoretically guaranteed accuracy analysis. In this talk, I'll present some of our approximation algorithms for the construction of fault-tolerant virtual backbone of a wireless sensor network, which can be modeled as a (k,m)-connected dominating set in a graph. The focus will be put on the methods and developing ideas for the designing and analyzing.
