在多跳无线传感器网络（WSN）中，距离Sink一跳的节点首先死亡，并造成“能量洞”，因为它们必须转发来自网络其余部分的流量。当这个洞形成时，大量的“多余”能量被困在其他节点中。在本文中，我们建议，这些其他节点使用一些多余的能量做合作传输（CT）直接跳到汇，从而减轻了一些他们的负担和平衡整个网络的能量消耗的汇附近的节点。当沿着主路由的下一个节点沿着具有比当前节点更低的剩余能量时，REACT协议触发CT范围扩展。本文考虑了选择合作者的几个标准，并通过仿真将我们提出的方案与AODV和CMAX多跳协议进行了比较。
In a multi-hop wireless sensor network (WSN), the nodes that are one hop away from the Sink die first and cause an "energy hole," because they must forward the traffic from the rest of the network. When this hole forms, a large amount of "excess" energy is trapped in the other nodes. In this paper, we propose that some of those other nodes use some of the excess energy to do cooperative transmission (CT) to hop directly to the Sink, thereby relieving the nodes near the sink of some of their burden and balancing the energy consumption across the network. The REACT protocol triggers CT range extension when the nexthop node along a primary route has a lower residual energy than the current node. The paper considers several criteria for selecting the cooperators, and compares our proposed scheme to the AODV and CMAX multi-hop protocols through simulation.
