摘要：

Wireless sensor network (WSN) is a network of large number of interconnected nodes that can independently sense, process and transmit data between themselves and to the base station. Video wireless sensor network (VWSN) is used for capturing and transmitting video data. In VWSN each node consists of camera, memory, processing unit, communication unit and battery. Due to the small size and limited battery life of the node, transmission of video data is a challenging task, as it requires larger bandwidth and more processing power. This paper primarily focuses on energy optimization which is achieved by compression of video at the first stage by using DCT lossless compression technique and then selection of the nodes for transmitting this video using 'Low Energy Adaptive Clustering Hierarchy' (LEACH) protocol. In LEACH protocol cluster head nodes are randomly selected in order to achieve even energy distribution.
