Name: SOS

TItle: A dynamic operating system for sensor networks

Description: SOS is an operating system for mote-class wireless sensor networks developed by the Networked and Embedded Systems Lab (NESL) at UCLA. SOS uses a common kernel that implements messaging, dynamic memory, module loading and unloading, and other services. SOS uses dynamically loaded software modules to create a system supporting dynamic addition, modification, and removal of network services.

Status: Inactive Project
