Abstract—Results and lessons learned from the implementation of a novel ultra low-latency geo-routing scheme are presented in this paper. The geo-routing scheme is intended for team-based mobile cyber-physical systems whereby a cluster of unmanned vehicles (robots) are deployed to accomplish a critical mission under human supervision. The contention-free nature of the developed scheme lends itself to jointly achieve lower latency and higher throughput. Implementation challenges are presented and corresponding resolutions are discussed herewith. Index Terms—team-based mobile cyber-physical systems, un-manned aerial vehicles (UAV), mobile ad hoc networks (MANET), contention-free geo-routing, blind cooperative transmission, car-rier frequency offset (CFO), software-defined radios (SDR).

Abstract—Batch processing is a well-known concept in com-puter science and widely used to improve performance in many applications. Similarly, to improve the delivery ratio and end2end delay in wireless sensor networks (WSNs), we propose to use batch forwarding instead of streaming. Our main goal in this paper is to evaluate and compare the performance of batch forwarding and that of streaming. Accordingly, we first develop analytical models under simplified assumptions. We then conduct extensive actual experiments using TinyOS and IRIS motes from Crossbow. Both analytical and actual experimental results show that batch forwarding significantly improves the efficiency and delivery radio, particularly in heavily loaded network en-vironments. Despite some delay due to batch formation, batch forwarding also improves the overall end2end delay performance due to its efficient use of resources. As a result, batch forwarding is a viable data gathering solution and must be used in WSN applications that generate significant amount of sensing data and require high delivery ratio and less delay.
