In order to solve the problem of excessive energy dissipation due to long distance transmission among cluster-heads, a virtual backbone network algorithm based on the multilevel cluster tree with gateway is proposed. Some reasonable cluster-heads are found using the maximal independent set with maximal weight. By introducing some gateway nodes as relay transmission among cluster-heads, network lifetime is further prolonged. The simulation results show that the algorithm bears efficiency and low complexity.
