18、tc. But there are many different sensor network implementations and they are not interoperable. In general, sensor networks are developed according to the sensor network applications requirements (in which ways sensor network applications use sensor networks) within sensor network hardware constrain
19、ts. When it comes to sensor network applications requirements, they include transport-level requirements, sensor networks hardware point of requirements, applications operational requirements, etc. Of these requirements, applications operational requirements affect sensor network implementations, ev
20、en though each sensor network supports the same transport protocol and uses the same hardware specification. However, these applications operational requirements can be generalized and can be used to derive standard application layer interfaces between sensor networks and sensor network service prov
21、iders. This International Standard specifies generic sensor network application interfaces based on the generalized sensor network applications operational requirements with consideration on sensor network hardware constraints.

43、 The keyword “should” is used to indicate that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required, or that (in the negative form) a certain possibility or course
44、 of action is deprecated but not prohibited. The keyword “may” is used to indicate a course of action permissible within the limits of the document. The key word “can” is used for statements of possibilit y and capabilit y, whether material, physical or causal. 6 Overview of sensor network applicati
45、ons 6.1 Communication model Sensor network applications provide sensor-associated or actuator-associated services for users by interacting with at least one sensor network. When it comes to sensor network service providers, they need to communicate with lots of different types of sensor networks to
46、provide integrated services for users. On the other hand, sensor networks provide sensor network services to multiple sensor network service providers to maximize their benefits. In this context, the communication model between sensor network service providers and sensor networks can be summarized i
47、n two cases. In one case, an interface is defined by a sensor network that provides sensor network services based on the interface. Then, sensor network service providers implement the interface defined by each sensor network to communicate with the sensor network. This case is illustrated in Figure
48、 1. If there is no standard interface between sensor networks and sensor network service providers, sensor network service providers need to implement different interfaces to communicate with different sensor networks. In Figure 1, the sensor network service provider needs to implement interface A,
49、interface B, and interface C altogether to provide integrated services for users. In view of that there are many different sensor network providers in the world, implementing all of these sensor network providers interfaces is a tedious and time consuming process, and it is definitely not a good solution.4 ISO/IEC 2014 All rights reservedBS ISO/IEC 30128:2014ISO/IEC 30128:2014(E) Figure 1 Communication model: Multiple sensor networks and one
