Ad-Hoc Wireless Protocol Simplification for IEEE 802.16
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, such as Bluetooth and Wi-Fi, are limited in range and complexity, making them unsuitable for ad-hoc networks beyond short distances, whereas IEEE 802.16 standards are designed for longer ranges but have complex protocols that are not adopted in industrial standards like WiMAX and WiBro.
Innovation Solution
A simplified communication protocol for ad-hoc mode communication using IEEE 802.16 standards, which allows mobile stations to operate without a base station, using a server mobile station to establish a wireless channel with continuous frames and simplified ranging, broadcast management, network entry, and bandwidth allocation, enabling compatibility with WiMAX and WiBro specifications.

1Length of stationary object
If IEEE 802.16 protocol is used for ad-hoc communication, then communication range is extended, but protocol complexity increases
Solution Approach 1:
The patent segments the IEEE 802.16 protocol into two distinct modes: infrastructure mode (for long-range communication with base stations) and ad-hoc mode (for short-range peer-to-peer communication). By separating these functions, the patent allows devices to use only the necessary protocol components for ad-hoc communication, reducing complexity while maintaining extended range capability when needed.
Solution Approach 2:
The patent extracts and removes complex protocol elements from the ad-hoc communication mode, retaining only the essential features needed for peer-to-peer communication. This extraction simplifies the protocol for ad-hoc operations while preserving the ability to leverage IEEE 802.16's long-range capabilities when infrastructure mode is used.
2Device complexity
If simplified communication protocol is used for ad-hoc mode, then device complexity is reduced, but communication reliability may be compromised
Solution Approach 1:
The patent applies local quality by implementing different protocol complexity levels in different operational contexts. In ad-hoc mode, the protocol is simplified for lower complexity, while in infrastructure mode, the full IEEE 802.16 protocol is used for higher reliability. The system automatically selects the appropriate mode based on the presence of a base station, ensuring reliability is maintained where needed without unnecessarily increasing complexity.

AI summary
An embodiment of the present invention is a technique for short-range ad-hoc mode communication. An ad-hoc mode is configured for a first mobile station (MS) operating in an ad-hoc network under a broadband wireless standard. An ad-hoc mode communication is acquired having a simplified communication protocol of the broadband wireless standard. A second MS is communicated with using the ad-hoc mode communication.
