查询词典 ad hoc

The minimality of the virtual backbone is assured by designing optimization algorithm. As a result, it can effectively decrease the overhead of control packets dissemination. Simulation resluts show the correctness and the ability of self- renew.Considering the characteristic of fast-moving in wireless ad hoc networks, we construct a virtual backbone with a independent dominating set. This method can avoid sustaining connectivity between backbone nodes and the bakebone network can be rapidly reconstructed as topology change.
