Abstract Integration of sectored antenna in wireless networks improves network performance through increased network capacity and extended transmission range. However, incorporating sectored antenna makes the trivial process of discovering neighbors even more challenging and complicated. Moreover, due to the duty-cycled nature of Wireless Sensor Networks (WSNs), self-adaptive and distributed neighbor discovery mechanisms are highly sought-after. In this paper, we present a Neighbor Discovery with Sectored Antenna (NDSA) protocol for WSNs with the sectored antenna. NDSA distinguish itself from other protocols in four distinct ways. Firstly, the introduction of super-frame like structure to support the duty-cycled operation of WSNs. Secondly, the protocol adapts its operation according to the network dynamics by leveraging the in-network information. Thirdly, a cooperative mechanism through which nodes utilize the information about their discovered neighbors to avoid an excessive exchange of control messages. Finally, handling the channel access details to discover neighbors faster with fewer message collisions. Through a comprehensive simulation-based study, the results show that the proposed protocol outperformed the random and serialized approaches to neighbor discovery in terms of discovery latency while significantly minimizing the communication overhead.

具有扇形天线的无线传感器网络中的自适应邻居发现

摘要 在无线网络中集成扇形天线通过增加网络容量和扩展传输范围来提高网络性能。然而，结合扇形天线使得发现邻居的微不足道的过程更具挑战性和复杂性。此外，由于无线传感器网络 (WSN) 的占空比性质，自适应和分布式邻居发现机制非常受欢迎。在本文中，我们提出了一种带有扇区天线的邻居发现（NDSA）协议，用于带有扇区天线的 WSN。NDSA 以四种不同的方式将自己与其他协议区分开来。首先，引入类似超帧的结构来支持 WSN 的占空比操作。其次，协议通过利用网络内信息根据网络动态调整其操作。第三，一种协作机制，通过该机制，节点利用有关其发现的邻居的信息来避免过度交换控制消息。最后，处理通道访问细节，以更少的消息冲突更快地发现邻居。通过全面的基于仿真的研究，结果表明，所提出的协议在发现延迟方面优于随机和序列化的邻居发现方法，同时显着减少了通信开销。
