In wireless ad hoc networks, neighbor discovery is necessary as an initial step. In this work we present LECDH (Low Energy Collision Detection Hello), an energy-aware randomized handshake-based neighbor discovery protocol for static environments. We carried out simulations through Castalia 3.2 simulator and compared LECDH with an existing protocol EAH (Energy Aware Hello) used as reference. We conclude that the proposal outperforms the reference protocol both in one-hop and multi-hop environments in terms of Energy consumption, Discovery time, Number of discovered neighbors, Throughput, and Discoveries per packet sent, for high duty cycles. Moreover, for low number of nodes in LECDH, as the duty cycle is reduced the performance is better according to all 5 metrics in both environments. Overall, we found that our proposal follows more realistic assumptions and still allows nodes to succeed at discovering all their neighbors almost with probability 1. Moreover, a qualitative comparison of the reference solution and our proposal is included in this paper.

在无线自组织网络中，邻居发现作为初始步骤是必要的。在这项工作中，我们提出了 LECDH（低能量碰撞检测 Hello），一种用于静态环境的能量感知基于随机握手的邻居发现协议。我们通过 Castalia 3.2 模拟器进行了模拟，并将 LECDH 与用作参考的现有协议 EAH（Energy Aware Hello）进行了比较。我们得出结论，在高占空比的情况下，该提案在能耗、发现时间、发现的邻居数量、吞吐量和每个发送的数据包的发现方面都优于单跳和多跳环境中的参考协议。此外，对于 LECDH 中的少量节点，随着占空比的降低，根据两种环境中的所有 5 个指标，性能会更好。全面的，
