Design of a Decentralized Frequency-Hopping Wireless Networking Product

Introduction: In 2013, I worked on a project that implemented a decentralized, self-organizing, multi-hop routing wireless network product based on Ad-Hoc wireless network technology, which operates without a central infrastructure. Project Requirements: The goal was to achieve a decentralized frequency-hopping network among 6 nodes using Ad-Hoc wireless mode. Hardware Selection: At that time, the market … Read more

An Overview of Wireless Sensor Networks and Data Exchange

Wireless networks can be divided into two types. One type is infrastructure-based networks, which require fixed base stations, such as mobile communication networks that need tall antennas and high-power base stations for support; the other type is infrastructure-less networks, including mobile Ad Hoc networks and wireless sensor networks (WSN), where the nodes are distributed without … Read more

Understanding IBSS (Ad-Hoc) Mode in Wi-Fi Networks

Understanding IBSS (Ad-Hoc) Mode in Wi-Fi Networks 1. Basic Concept of IBSS In wireless networks, IBSS (Independent Basic Service Set) is a network topology defined by the IEEE 802.11 standard, also known as Ad-Hoc mode. Unlike the common Infrastructure Mode, IBSS allows multiple devices to communicate directly without the need for an Access Point (AP), … Read more
