“…The deadline of data packet delivery should be shorter than the response time, and we set it to 120 seconds (2 minutes). Besides, the capacity of nodal storage modules is extremely limited (the space memory is even measured in KB or MB [30], e.g., the chip CC2430 has a flash memory of 128 KB [33]), and we set = 30, 000 KB in the following simulations.…”

The opportunistic mobile sensor network has been extensively applied in various public safety applications such as the fire rescue and earthquake rescue, since it can provide a surveillance range with an inexpensive cost and avoid the dangers of humans staying in risk zones. However, due to some environmental events such as building structure damage, airflow push, and fire explosions, the sensor nodes sprinkled into the fire-rescue scenario may be kept moving. Thus, the contacts between nodes become momentary, and the data packets cannot be forwarded along stable communication paths. To this end, the opportunistic forwarding manner is adopted in the fire-rescue scenario to enable the data packets to be transferred to the rescue control center (RCC) through some discrete hops. The contributions of this paper are threefold. First, the nodes in the fire-rescue scenario are carefully investigated and classified into four types: small-range mobile nodes (SRNs), large-range mobile nodes (LRNs), firefighter nodes (FNs), and robot nodes (RNs). Second, we formulate the data forwarding problem, and the optimal proportions of SRNs, LRNs, and FNs in data holders are mathematically analyzed to obtain the maximum delivery ratio. Third, a data forwarding approach for fire-rescue scenario (DFAFR) is proposed. In DFAFR, the optimal proportions of SRNs, LRNs, and FNs in data holders are maintained as far as possible through selecting different types of data holder candidates, and then the new data holders are determined from these data holder candidates and the adjacent RNs on basis of their expected delivery delay. Finally, the performance of DFAFR is analyzed through simulations of the fire-rescue scenario, and the results indicate that DFAFR can enhance the delivery ratio and shorten the delivery delay while the forwarding overhead is restricted.

The application of Static Random-Access Memory (SRAM), becomes more and more widely in aviation. However, the large amount of SRAM cells is very vulnerable to radiation included single-event upset (SEU). Based on the detection requirement of SRAM's SEU, the detected circuit of the SEU on SRAM is designed. Then the method of redundancy check is used in the reinforcement of the SEU. The test results shows that the detection circuit can detect the SRAM-type storage chip sensitive bit of the single particle and the proposed method can improved the performance of anti-single particles of SRAM several times as high as 1E6.
