Load-Balanced Virtual Backbone Construction for Wireless Sensor Networks,, the Load-Balanced Virtual Backbone (LBVB) problem, and the MinMax Valid-Degree non Backbone node Allocation (MVBA) problem. We claim that MDMIS and LBVB are NP-Complete and MVBA is NP-Hard. Moveover, approximation algorithms and comprehensive theoretical analysis of the approximation factors are presented in the paper.

Load-Balanced Virtual Backbone Construction for Wireless Sensor Networks,ed VBs are competitive approaches among the existing methods used to establish VBs in WSNs. Most existing works focus on constructing Minimum-sized CDSs (MCDSs). However, few works consider the load-balance factor. In this work, the size and the load-balance factor are both taken into account when c
