协作中继网络以其高效性在智能电网应用中发挥着重要作用。然而,需要进一步改进能量和带宽管理,以延长网络生命周期并减少潜在的网络分段。为了均衡网络能量消耗,提出了一种基于机会的自适应中继节点选择算法(OAR)。在OAR中,潜在的中继节点被选为候选人的基础上的比特错误率(BER)的估计,然后,中继是自适应和机会主义地确定数据包转发。为了避免某些节点能量消耗过快,节点的剩余能量被考虑。仿真结果表明,OAR算法通过推迟节点的最早死亡时间和延长网络生命周期,提高了网络性能。
The collaborative relay network plays an important role in a smart grid application thanks to its high efficiency. However, energy and bandwidth management need to be further improved to extend network life cycle and reduce potential network segmentation. Aiming to balance the network energy consumption, this paper proposes an adaptive relay node selection algorithm based on the opportunity (OAR). In OAR, the potential relay nodes are chosen to act as candidates based on bit error rate (BER) estimation, and then, the relay is adaptively and opportunistically determined for packet forwarding. Residual energy is considered to avoid fast energy exhaustion for some certain nodes. The simulation results show that the proposed OAR algorithm improves the network performance by deferring the earliest death time of the nodes and extending the network life cycle.
