Introduction of embedded:
Embedded system debugging involves more conceptual layers of a target system than debugging for time-sharing systems. Consider the case of debugging a C program within a time-sharing system. User-debugger interaction occurs almost entirely at a C language level of abstraction. Descent into assembly language and machine code representations of a target program is rare. Suspicions about a compiler bug may require inspection of generated assembly code.
Wireless
Wireless telecommunications, is the transfer of information between two or more points that are physically not connected. Distances can be short, as a few meters as in television remote control; or long ranging from thousands to millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice, keyboards and headsets, satellite television and cordless telephones.
Abstract:
Design of a wireless sensor network based on Zigbee/IEEE802.15.4 is issued. The network is used to monitor the safe state of intelligent community and give alarm. Each sensor node in the system is composed of sensors and an integrated chip CC2430. The GPRS technology is used to complete data exchanging between remote monitoring center and wireless sensor subnets. This system is an application in intelligent community field.
