Reliable transmission is one of the key objectives research on wireless network optimization. The backpressure-based Max-Weight Scheduling (MWS) policy theoretically proven to be optimal solution for achieving highest available throughput. On other hand, proactive routing protocols, such as Optimized Link State Protocol (OLSR), are able compute reliable paths, which, in turn, can used a basis MWS-based resource allocation. However, its standard implementation, OLSR single-path protocol,...

Traditional measuring devices separate probes from their data visualisation, requiring the operator to switch attention between metering and result frequently. We explored efficiency of four different visualisation modalities during a circuit analysis task that utilises output an oscilloscope. argue spatial alignment oscilloscope's display probe interferes with cognitive processing visualisations, hence increasing probability errors required time. compared fixed placed oscilloscope, in-situ...
