TikiriDev: A UNIX-Like Device Abstraction for Contiki

Wireless sensor network(WSN) operating systems have resource constrained environments. Therefore, the operating systems that are used are simple and have limited and dedicated functionalities. An application programmer familiar with a UNIX-like operating system has to put a considerable effort to be familiarized with WSN operating systems' Application Programming Interface(API). Even though, UNIX-like operating systems may not be the correct choice for WSNs, some of their powerful, yet simple abstractions such as file system abstraction can be used to overcome this issue. In this paper, we discuss a UNIX-like file system abstraction for Contiki. File system abstraction is not the panacea. However, it adds to the repertoire of abstractions provided by the Contiki, thus easing the task of the application programmers.
