能量有效的层次跨层设计:Ad Hoc网络的联合功率控制和路由

On Energy Efficient Hierarchical Cross-Layer Design: Joint Power Control and Routing for Ad Hoc Networks

Cristina Comaniciu, H. Vincent Poor

摘要:

本文提出了一种层次化的跨层设计方法,通过节点发射功率和路由选择的联合自适应来提高Ad Hoc网络的能量效率。该设计保留了经典OSI模型的优势,同时通过信息共享考虑了层之间的交叉耦合。所提出的联合功率控制和路由算法显着增加网络的整体能源效率,在适度增加的复杂性为代价。还研究了使用多用户检测的联合设计的性能增强,结果表明,对于给定的能量消耗水平,使用多用户检测可以显着增加Ad Hoc网络的容量。

英文摘要:

In this paper, a hierarchical cross-layer design approach is proposed to increase energy efficiency in ad hoc networks through joint adaptation of nodes' transmitting powers and route selection. The design maintains the advantages of the classic OSI model, while accounting for the cross-coupling between layers, through information sharing. The proposed joint power control and routing algorithm is shown to increase significantly the overall energy efficiency of the network, at the expense of a moderate increase in complexity. Performance enhancement of the joint design using multiuser detection is also investigated, and it is shown that the use of multiuser detection can increase the capacity of the ad hoc network significantly for a given level of energy consumption.
