Buffering mechanisms play a vital role in leveraging the capacity and efficiency of live streaming as well as P2P streaming system. An appropriate buffering mechanism allows the peer to undergo a smooth playback by compensating the delay introduced by the network as well as storing pieces to be played in the near future. A circular buffer is used most of the time in a live P2P streaming system as the media duration is not known in advance.

The wide proliferation of WSNs in various domains has lead to the emergence of numerous applications having all different requirements. Consequently, different approaches and communications protocols have to be developed to meet these diverse and specific requirements. Moreover, network lifetime, as a major constraint of WSN, should be considered in the design of protocols for such networks. To this end, duty cycling technique is almost adopted.
