Wireless Image Sensor Network (WISN) is a type of sensor network, which has the ability of capturing, processing and transmitting images from a monitored environment. The need to improve the performance of such systems can be attained by using the Selective Cooperative diversity with ARQ (SCA) technique, which is basically a cross-layer design that combines Truncated ARQ at the link layer and cooperative diversity at the physical layer. In addition, the LEACH protocol has the advantage of utilizing randomized rotation of local cluster-heads to evenly distribute the energy load among the sensors in the network.
