摘要
由于Ad hoc网络是能量受限网络,因此如何提高Ad hoc网络的能量效率问题非常重要.该文提出了一种新的路由选择度量,该度量把节点链路层的拥塞度与节点当前剩余能量综合在一起考虑,使得网络中能量消耗和网络负荷能更加均匀地分布,提高了网络的连通性,增加了网络的吞吐量.仿真结果表明,该度量对于不同规模的网络,其吞吐量均有不同程度的提高.
Ad hoc network is an energy-limited network. How to improve energy efficiency in an Ad hoc network is an important open problem. This paper proposes a new routing metric, which integrates congestion status at the link layer and remaining energy of a node. By adopting this new metric, energy dissipation and traffic load are distributed more evenly in the network, leading to higher network connectivity and network throughput. Simulation results show that the new metric improves network throughput for networks with different scales.
