节点密度对优化Ad Hoc网络生存期的影响的研究

Study on the Effect of the Nodal Density on Optimizing Ad Hoc Network Lifetime

节点密度会限制拓扑控制策略对Ad Hoc网络生存期的有效优化范围.通过推导节点密度决定下的拓扑控制力的饱和状态趋向约束条件,阐述了节点密度与网络生存期的优化程度及拓扑控制性能分析之间的关系.通过实验仿真验证发现,在Ad Hoc网络中,通过平均度约束的拓扑控制确实可以延长网络生存期;而且,在节点密度的制约下,拓扑控制策略对网络生存期的优化将会达到饱和.

Nodal density limits the effective work range of the topology control strategy for optimizing the Ad Hoc network lifetime. Through deducing a constraint on the topology control ~ saturation trend, this paper presents the relationship between the network nodal density and both the network lifetime~ optimized level and the topology control performance analysis. Further simulations not only show that the average -degree constraint topology can prolong the network lifetime in the Ad Hoc network, but also show that under the constraint of nodal density, the optimization of the network lifetime controlled by topology will reach saturation.
