however this work is based on the UMTS PSN, the video could not send to the
mobile user directly. It is well known that the UMTS circuit switched video
system is a QOS guaranteed system. Targeted to solve such a problem; we
designed and implemented a prototype system, providing a novel architec-
ture to communicate between the WSN and UMTS to move video from a sen-
sor to a 3G handset user at low cost and power. Our previous work [1] mainly
focused on the video conferencing for 3G wireless network and 3G-324M pro-
tocol implementation [2-6]. Figure 3.3 shows a sensor node in WSN.
3.3.1 Sensor Network Frameworks
Several approaches are suggested to allow communication between the gate-
way and the user. Three of these methods in current usage have significant
disadvantages with respect to the main constraints related to sensor networks:
power, consumption, and cost. However, the advantages of this approach,
presented in this chapter for the first time, are to be available to all organiza-
tions with lower cost and lower power consumption.
The interoperability framework for sensor and UMTS network (IFSUN)
approach, which will be explained later in this chapter, moves data from
the gateway to the user at a lower cost and power by using the Universal
Mobile Telecommunication System (OJMTS), which is standard for the Third
