LiteOS
LiteOS is a lightweight, open source IoT device and smartphone OS from the Chinese smartphone manufacturer Huawei.
LiteOS is designed to have a low footprint, which saves space and reduces the load of the OS on the device. The operating system is made available on a BSD license, which is a class of simple, free licenses for computer software that was originally developed at the University of California at Berkeley. LiteOS supports smartphones, wearables, intelligent manufacturing applications, smart homes and Internet of Vehicles (IoV). The OS also serves as a smart device development platform. The platform simplifies IoT device development and connectivity, while also focusing on enhancing user experience (UX).
The kernel of Huawei’s LiteOS weighs in at a very light 10KB. Partially because of the compact size, the OS's fast start is down to milliseconds. The device is energy-efficient, helps devices conserve power and can be powered by a single AA battery for five years, according to Huawei.
Protocols supported for IoT devices include Zigbee and BLE, along with a number of cloud platforms. In contrast with Google’s Android Things OS, LiteOS can be run on devices with much less powerful hardware.
