能量收集技术潜在地解决了能量效率问题，这是无线传感器网络中最大的挑战。传感器节点具有从周围环境中收集能量的能力，能够实现无限寿命。该技术有望改变无线传感器网络通信协议的基本原理。协议应该保证收集的能量等于或大于消耗的能量，而不是尽可能多地节省能量。同时，这些协议被设计成具有高效的操作和最大的网络性能。在本文中，我们提出了ERI-MAC，一个新的接收器发起的MAC协议的能量收集传感器网络。ERI-MAC利用接收方发起和分组级联的优势，在延迟和能效方面都实现了良好的性能。此外，ERI-MAC采用了一种自适应机制，根据周围环境的能量收集率来调整传感器节点的操作。我们已经广泛评估了ERI-MAC在一个大规模的网络与现实的交通模型，使用网络模拟器NS-2。仿真结果表明，ERI-MAC协议具有良好的网络性能，并使传感器网络具有无限的生命周期。
Energy harvesting technology potentially solves the problem of energy efficiency, which is the biggest challenge in wireless sensor networks. The sensor node, which has a capability of harvesting energy from the surrounding environment, is able to achieve infinitive lifetime. The technology promisingly changes the fundamental principle of communication protocols in wireless sensor networks. Instead of saving energy as much as possible, the protocols should guarantee that the harvested energy is equal to or bigger than the consumed energy. At the same time, the protocols are designed to have the efficient operation and maximum network performance. In this paper, we propose ERI-MAC, a new receiver-initiated MAC protocol for energy harvesting sensor networks. ERI-MAC leverages the benefit of receiver-initiated and packet concatenation to achieve good performance both in latency and in energy efficiency. Moreover, ERI-MAC employs a queueing mechanism to adjust the operation of a sensor node following the energy harvesting rate from the surrounding environment. We have extensively evaluated ERI-MAC in a large scale network with a realistic traffic model using the network simulator ns-2. The simulation results show that ERI-MAC achieves good network performance, as well as enabling infinitive lifetime of sensor networks.
