<p>Embedded systems that monitor and control safety and mission critical system are communicated with by a HOST located at a remote location through Internet. Such kind of embedded systems are developed to be dynamically evolvable with respect to syntax, semantics, online testing and communication subsystems. All these systems are to be dynamically evolvable and the components needed for evolution are also to be added into the embedded system. Architectural  models describe  various components using which dynamically evolvable sub-systems are realised through implementation by using specific and related technologies. Implementation system describe the platform, code units and the interlacing of various processes/tasks to the elementary level of details. WEB services place an excellent platform for implementing dynamically evolvable  systems due to the use of open standards.</p><p> </p><p>This paper presents an implementation system that is related to dynamically evolvable communication and other sub-systems using web services technologies.</p>

In this paper we present a decoupled architectural approach that allows software agents to interoperate with enterprise systems using Web services. The solution leverages existing technologies and standards in order to reduce the time-to-market and increase the adoption of agent-based applications. We present case studies of applications that have been enhanced by our proposal.

Embedded systems are extensively used in the field of pervasive computing. These systems are used to such an extent that embedded systems are now controlled and monitored from remote locations by using Web services. Internet authorities are able to assign every device a unique Internet protocol address with the introduction of IPv6 on the Web. Peer-to-peer communication between Internet-enabled devices helped Web services to make performance improvement. On the worse side, it created new attacks on the components used in the embedded systems. The chapter discusses the details of security issues on a Web-enabled embedded system used in greenhouse environment. The devices used in greenhouse environment are monitored and controlled by different software components used in the entire system. Various vulnerabilities are introduced during entire development process of the greenhouse environment. The problem is to search the real threats, then define security policies and implement them during development process. The chapter discusses most of the vulnerabilities of a generalized greenhouse project and tries to find out possible security techniques to deal with the vulnerabilities. Instead of showing the design to build a greenhouse embedded system, it shows to introduce security policies at various levels of life-cycle, be it before development, during development, or after development.
