1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
In Consideration for the application of telemedicine and smart manufacturing which require a sensing devices with flexible nature, small form factor, ultra low-power consumption in a local sensing network, current network architecture is apparently not sufficient to support efficient and effective operation. For example, it is not appropriate for a smart clothing for function of motion capturing with multiple sensors working simultaneously, by using wireless network such as Bluetooth (BT) due to its limit of network capability, bandwidth and nature of peer-to-peer communication scheme., or by existing WiFi network majorly due to its un-acceptable power consumption using battery. On the other-hand, It is almost not possible to apply existing wired network directly to flexible electronics due to its bulky nature( Ethernet) and limit network capability( RS232, SPI, I2C, etc..) , Therefore, a new network architecture, LASN (local area sensing network), and its associated protocol for flexible electronics is required. We propose a network architecture with mixed 2-wire and wireless network (revised BT) to cover the problem addressed above.
Top issue among the problem for a network when number of devices increased, is the device ID (address) assigned. It is required to dynamically assign an unique address to each individual device considering the usage scenario such as manufacturing process, capability of hot join and maintenance and etc. Therefore, it is required to create a smart addressing mechanism to cover the mentioned issues.


b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: Telemedicine and smart manufacturing

c. Estimate technical difficulty of the activity.
III: Difficult - Limited expertise and resources exist and/or achieving consensus is difficult

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
The scope of this FHE Local Area Sensing Network (LASN) task force will aim to explore and develop standards for local area sensing network to ensure effective and efficient communication between sensing devices, and between devices and sensor hub to existing Ethernet-based network architecture.
This includes developing standards and guidelines for sensing network architecture, associated bus protocol, definition of attribute of sensing devices, method of local data fusion, collaborated computing of edge devices, and etc., within limited bus capacity and available power resource.

Top issue among the problem for a network when number of devices increased, is the device ID (address) assigned. It is required to dynamically assign an unique address to each individual device, considering the usage scenario such as manufacturing process, capability of hot join and maintenance and etc. Therefore, this standard focuses on system architecture, protocol and a smart addressing mechanism to cover the mentioned issues in rationale.

It will also seek to support the supply chain needs for improving FHE product / process in a synchronized manner for Local Area Sensing Network applications.
