19、as industrial automation, environment monitoring, smart home, intelligent health-care and smart grid. The applications can involve different devices supplied by different manufacturers, e.g. sensors, actuators, controllers, routers and gateways, etc. Data can be collected and processed by use of dif

20、ferent wired/wireless communication technologies. Thus, various test systems should be employed to satisfy some specific requirements. The operations of test systems is a challenge to users, if without a uniform test platform. When designing and developing a sensor network test system, the character

21、istics regarding the following aspects should be considered: a) Sensor network heterogeneity. It is necessary to verify the interoperability of sensor networks based on different protocols prior to system application; b) Diversity of sensor network applications. However, an international test standa

22、rd for sensor networks which can provide guidance to design and develop a uniform platform integrating different tests for sensor networks is still unavailable.

32、ments of sensor networks Varied with applications, sensor networks are likely employ different communication technologies and protocols. To ensure their interconnection and operation, it is required to deploy a great number of test systems, which are designed to test individual technologies and prot

33、ocols with regard to protocol conformance. Therefore, it is a challenging task to integrate the variety of the test systems for sensor networks. It is difficult to manage different test systems, make them work together and execute test cross various technologies and protocols for specific user requi

34、rements. Various application systems need different communication interfaces and protocols, which cant interact directly with each other. With changing testing requirements, test system for sensor networks should be scalable and adaptable on demand. For example, when new sensor networks are added in

35、to the application, the corresponding test systems should be integrated into the test platform with low costs. Annex A describes an example of a testing platform for hybrid sensor networks based on IPv6.2 ISO/IEC 2016 All rights reservedBS ISO/IEC 19637:2016ISO/IEC 19637:2016(E) 5.2 Conceptual model

36、 of SNTF Figure 1 shows the concept model of SNTF. The framework consists of three parts: test manager (TMR), test agent (TA) and system under test (SUT). As an actual management controller, the TMR conducts a test indirectly by controlling the TA. The test activities of the TMR should be converted

37、into unified services and transferred to the TA. After having processed the testing services from TMR, TA conducts test interactions directly with SUT. Therefore, TA bridges TMR and SUT while TA needs to be equipped with the specific physical communication interface and protocol stack as in SUT. The

38、 SUT is a system that can include only one device under test (DUT), or a DUT and some other devices used to activate the behaviours of the specific protocol residing in DUT, which is named auxiliary testing equipment (ATE). DUT needs to be verified for having certain required protocol implementation

39、s. SUT contains points of control and observation at the upper or lower service boundary of the protocol implementations that resides in DUT to execute tests. The protocol implementations during testing is called implementations under test (IUT). Before starting performing the conformance tests, IUT

40、 should be configured by instructions from TMR. In a complicated environment, ATE can be used to stimulate the DUTs to ensure TAs observe the expected responses from DUT if the IUT cant activate some particular behaviours of protocol by itself.

Each TAP has a specific test task to be performed. For example, it can create an application process for conformance testing of a particular

42、protocol, and simultaneously another application process for a different protocol. The testing application process is designed on a component basis. There are five types of components in a TAP: view object, test report, test module, analysis module, and object dictionary (OD). Figure 2 shows the rel

43、ationship of the five components. The test module (TM) is the performer of test cases. Before executing a test, TM should be parameterized to configure the test type for a specific protocol. If the corresponding testing requirements and testing suits are inputted into a TM, it is instantiated. After

44、 the TM is started, the steps defined by test cases is executed. The analysis module (AM) shall connect test modules to collect data to analysis test activities. It is needed to configure the corresponding report format in the AM before producing test reports. Moreover, AM can also collect the infor

45、mation of the operating conditions of the TM. The view object (VO) has parameter sets from the TMs and AMs. VO can be selected for graphical user interfaces, which allows monitoring the real-time throughput during a certain period. VOs also can be grouped to monitor the parameters in the relevant TM

46、s and AMs; its visual parameters can also be derived from different TMs or AMs. Management information base (MIB) stores all object values of test module, view object and test report in TMR, including the management objects for TA. The values of the objects in testing application process can be inde

47、xed quickly from object dictionary (OD). Figure 2 Relationship of components in TAP4 ISO/IEC 2016 All rights reservedBS ISO/IEC 19637:2016ISO/IEC 19637:2016(E) 5.4 Description of test agent (T A) A test agent (TA) is designed for individual protocol, and it can support multiple implementations of th

48、e same protocol. The TA handles any direct communications with the SUT with the same protocol through the test driver. Platform independence can be achieved by the test driver. The configuration parameters of test driver are defined in the TA description. Before performing the corresponding test ope

49、rations, TA shall establish communication connection with TM in TMR when receiving the start command from a TM. TA receives services from TM and translates them into the appropriate messages in conformance with the protocol of SUT. Structure model of TA is shown in Figure 3. Figure 3 Structure of TA 6 Testing services 6.1 General Testing services are conceptually divided into two classes: testing data services (TDSs) and testing management services (TMSs) as shown in Figure 4
