Batch processing is a well-known concept in computer science and widely used to improve performance in many applications. Similarly, to improve the delivery ratio and end2end delay in Wireless Sensor Networks (WSNs), the authors propose to use batch forwarding instead of streaming. The main goal in this paper is to evaluate and compare the performance of batch forwarding and that of streaming. Accordingly, they first develop analytical models under simplified assumptions. The authors then conduct extensive actual experiments using TinyOS and IRIS motes from Crossbow.
