Wireless Sensor Networks (WSN) has seen almost a decade of active research. The concept of Wireless Multimedia Sensor Networks has been derived from WSN where the focus has shifted from low data rate random infrequent transmissions to high data rate regular transmissions in the network. In order to support multimedia transport like voice streaming in this highly constrained network, the protocols need to be optimized for the channel throughput and lifetime of the network required by the streaming application. The Medium Access Control (MAC) protocol plays an important role in the operation of this network to avoid collisions and allocate the optimum throughput to nodes in the streaming path.
