First introduced the concept of sensor network research and popular for cabletransmission network inadequate, discussion of wireless sensor network applications inthe transmission among the advantages of wireless communication, combined withtransport communications environment, analysis of the current shortcomings of currentwireless sensor networks, and gives the corresponding solution approach. Proposedcable plus wireless transmission methods.To solve the above problems, the paper bycomparing the various chip features and power, energy-saving wireless sensor modulemade of hardware design, implementation, communication, and designed a simplemulti-hop network communication protocols, not only for data transmission, and canrespond to emergencies, the network automatically re-organization.Finally the hardware design and software protocol improvements, given testing locationdata, proposed empirical formula. |
