Wireless Sensor Networks applications often need to be changed after deployment for a variety of reasons. Reconfiguring a set of parameters and patching security holes and modifying tasks of individual nodes. Wireless reprogramming is a crucial technique to address such challenges. Code Dissemination is a basic building block to enable wireless reprogramming. We present a link quality aware Sleep Scheduling Algorithm leveraging the 1-hop link quality information. It has following salient features compared to prior works. First it supports dynamically configurable packet sizes. Second it employs an accurate sender selection procedure to mitigate transmission collisions and transmission over poor links. Third it conserves energy and also takes short completion time.
