This paper is addressing the challenges of incorporating networking and security concepts into effective teaching and learning platform (PLab) that highlights real-world technical issues. PLab is an innovative portable learning platform that allows network applications to be safely tested. The isolated network without the need for a server promotes learning at anytime and anywhere. The strong connection...
The development trend of embedded technology need the web/server technology applies into embedded fields and provides a flexible remote device monitoring and management function based on Internet browser. But, due to the limitation of hardware resource and the low-efficiency of general purpose TCP/IP protocol stacks and protocol models, it is quite difficult to implement full TCP/IP protocol into...
This paper presents an integrated system for industrial data acquisition and monitor using CDMA 1x communication technology. In the system, a Slave Control Module (SCM), which can cache incoming data in buffer in case of emergency to avoid package loss, is designed. The wireless data transmission of the system is implemented with Data Terminate Unit (DTU), which is designed with CDMA 1x technology...
As a policy driven security mechanism, establishing a IPSec security policy control system requires a right modeling tool. Compared with other modeling languages, CPN provides a clear description to the status and action of system. In this paper, we try to adopt the abundant expressions of CPN to describe dynamic change of IPSec protocol., and establish a CPN model of IPSec protocol sender
This paper presents a home automation module with programmable control instructions (PCIs). Although it is implemented by using a low-cost 8-bit microcontroller with only 8 Kbytes of ROM spaces, a time-sharing task scheduler and 10 PCIs are included in the firmware. Timer and counter control, logic functions, and temperature control are examples of PCIs. Thanks to the design of pseudo nodes, these...
