Abstract:

       This paper surveys the total structure, hardware components of a node and the network protocol architecture for wireless multimedia sensor networks (WMSN). The paper also presents its most important key technologies that affect its applications-low timedelay and low power consumption network design. The paper further presents their probable breakthrough branches in future, low timedelay and realtime MAC, low timedelay and low power consumption routing, multimedia information security, development of multicore and manycore oriented multimedia terminal, multimode software component and high compression ratio based coding for multimedia traffic stream.

Key words: multimedia wireless sensor networks, wireless communications, multimedia communication networks
