With the introduction of trust mechanism into the wireless ad hoc network, security can be greatly improved, because trust information is shared among all nodes in the network. However, such a mechanism also has the potential vulnerability if the so-called 'big-mouth' nodes broadcast wrong trust information. Some measures have to be taken to filter the received trust information before it is fed to...
In this paper, data collection schemes with data aggregation for static sink are proposed in wireless sensor networks. According to the distribution of source nodes in whole sensor field, we use a block partition scheme and then each block selects a sensor node as local sink for the data collection of the local area. Furthermore, the local sink would transmit the data to the global sink after aggregating...
The mathematical model of intercooled cycle gas turbine was established and the relative simulation model was also built based on MATLAB/SIMULINK. Under a given structure size of intercooler, many magnificent conclusions were drawn over the analyses of influence of different liquid side flow parameters on the intercooler system performance. The simulation experimental results show the increase of...
The completely non-linear mathematical model of intercooled cycle gas turbine has been built according to the mechanism of thermal system modeling method, taking into account the impact on the gas turbine system such as rotational inertia, volume inertia, intercooler thermal inertia, and the relative dynamic simulation of the intercooled cycle gas turbine based on Matlab/Simulink has also been built...
Mobile ad hoc networks will often be deployed in environments where the nodes of the networks are unattended and have little or no physical protection against tampering. The nodes of mobile ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to denial of service (DoS) attacks launched through compromised nodes or intruders. In this paper, we investigated the...
This paper discusses the multi-state coherent system composed of multi-state components. First, using the min cut sets or min path sets, we present our simulation algorithm, instead of the general structure function, to calculate the probability that the system is in a specified state. Second, we check the components per period, e.g. one check per year, to obtain the state sequences of all components...
