| Abstract: | A terminal unit which has simultaneous audio and data transmit ability based on the JN5139 module is designed for applying it to a multimedia wireless sensor network,and the audio stutter problem caused by buffer underrun is solved.On the basis of Cluster+AODVjr routing algorithm,a routing strategy based on data type is proposed,which can prevent RREQ from flooding and can balance energy costs of the nodes.The sound quality is evaluated by using E-model,the result shows that the longest transmission distanc... |
