Mobile Ad Hoc Network (MANET) techniques are critical to the success of emerging modern warfare concepts and are required to support communications
for mobile military platforms, including ships, aircrafts, and ground vehicles operating in a highly dynamic and mobile tactical
communications network without fixed infrastructure. Research in Mobile Ad Hoc Networking has increased dramatically over the last few years with significant work in hardware architectures, media access
and routing protocols. Until now, most of the work has been in simulation and small-scale laboratory demonstrations due to
the significant resources required to implement an actual network with sufficient nodes to fully exercise the capabilities
of both the hardware and software. There is significant need to develop testbeds to fully understand the behavior of ad hoc networks, performance under real-world application scenarios. This paper describes a testbed for a real system application
exercised in an outdoor environment which approximates very closely the physical operational environment. The ad hoc network performance results include throughput and delay under conditions of mobility and foliage. 相似文献

Laparoscopic mapping of the phrenic nerve motor points using test stimulation was conducted for the implant of epimysial electrodes for diaphragm pacing in dogs. Both visual assessment of muscle activation and measurements of recruitment were useful for identifying an implant location resulting in a mean electrode placement approximately 14 mm from the phrenic nerve motor points in 16 dogs. Postmortem analysis of the stimulus test site locations and corresponding recruitment curves suggested that the phrenic nerve motor points could be predicted during the laparoscopic procedure to within 4.5 mm of the anatomical motor point. 相似文献
