UMR Mote-based Demonstration of Wireless Sensor Networking Protocols Using Pneumatic Testbed

Wireless sensor network (WSN) technology has the potential to revolutionize the ability of industrial, residential, safety, and military applications in terms of small, low-cost, and quickly deployable systems to bring observability to pertinent personnel. However, for some applications the existing solutions do not provide adequate quality of service (QoS). For example, timesensitive monitoring and control systems need guarantee of timely delivery of the information across the congested network and application constraints have to be taken into account during protocol development. The technical design issues have been discussed and protocol is developed to address these issues. At the University of Missouri-Rolla (UMR) ongoing research into the integration of distributed algorithms that can satisfy a wide array of user requirements is being pursued. The optimal energydelay sub-network routing (OEDSR) protocol and adaptive distributed fair scheduling (ADFS) has been developed and implemented on the UMR mote hardware. The integrated platform shows promise for delivering reliable WSN services to targeted applications. The OEDSR protocol is contrasted experimentally with AODV protocol. This demonstration focuses on presenting the capabilities of the UMR platform for development of network protocols and support of industrial applications, similar to the presented diagnostics of the pneumatic testbed. The network of 20 nodes will be presented with real and simulated data sources. The pneumatic testbed is equipped with a UMR mote that performs the diagnostics in real-time and provides observability through the network

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp
