TCP/IP Application Layer Protocols for Embedded Systems

Communication is fast becoming a general requirement for embedded systems in our increasingly connected world. In fact, it's difficult to find embedded systems that include no form of external communication. Embedded systems are now transmitting electric meter readings over low-bandwidth wireless links to alleviate the need to read them visually. Global Positioning System (GPS) technology and wireless links with embedded systems are also used to pinpoint the exact location, speed, oil pressure, and other parameters of fleets of trucks anywhere in the country. Creation of these and other networked applications are the focus of this book. Using practical tutorials on TCP/IP application layer protocols such as HTTP, SMTP, POP3, SNMP, and SLP, developers learn how to develop and deploy these protocols in their embedded systems. Key Features

• Provides original implementations of popular TCP/IP application layer protocols such as HTTP, SMTP, POP3, NNTP, SNMP, and SLP
• Explains the unique requirements and challenges of using Internet protocols in resource-constrained embedded systems
• Includes detailed coverage of the BSD networking APIs and relevant socket options
• Teaches through real-world examples that can be put to immediate use in embedded projects
• Discusses new protocols, such as SOAP, XML-RPC, SIP, SCTP, OSGI, IPSec, Web Services, and a variety of QoS protocols and architectures
