In this paper, two classes of stochastic optimization problems, which are expected value models and chance-constrained programming, are introduced. In order to solve the problems, the method of stochastic simulation is used to generate training samples for neural network, and then particle swarm optimization algorithm and neural network are integrated to produce a hybrid intelligent algorithm. Two numerical examples are provided to illustrate the effectiveness of the hybrid particle swarm optimization algorithm.

Smart antennas (SA) has not been applied widely in 3G except TD-SCDMA. As to the application of SA in CDMA system, we argued that people hold certain incorrect view, especial the reciprocity characteristic. Generally, people consider that only using a set of SA, we can simultaneously realize multiple CDMA channels directional transmission on a single carrier frequency with the same uplink & downlink SNR gain, and the transmitting beamforming can be realized by amplitude-weight transmitting baseband signal just like the receiving beamforming. For these views about the SA direction-transmission principle in CDMA system, we did careful analysis. We proved that these opinions mentioned above are incorrect. In order to take good use of smart antennas (SA) in the CDMA system, we also proposed a feasible carrier weight method.

In this paper we analyze wireless network and discuss the applications of wireless technology. In wireless network, the wireless devices should be able to operate independently of the broader Internet. In particular, there may be times during which the connection of a wireless device or network to the Internet is not available. During these times, wireless devices should be able to operate stably in modes disconnected from the rest of the infrastructure, as well as be able to opportunistically establish "local" ad-hoc networks using their own native protocols. This will require that devices are capable of discovering each other without the assistance of the broader network, as well as require that devices use local addressing and routing schemes.

In the application of wireless sensor networks (WSN), the balance of energy consumption plays an important role in extending the life cycle of WSN. Aim at energy consumption of Wireless sensors network, a dynamic cluster-based routing protocol based on the greedy algorithm (GDCRP). In the protocol, nodes run for the cluster head according to the energy and location. The elected cluster head has optimal value of energy and location. When the cluster is formed, the sink node initiates the request of routing establishment; the cluster heads choose the nodes that send it the packet as the upper nodes according to energy and hops count to the sink node. After a period of the network operating, then choose nodes according to the energy value and distance as the cluster head once again in order to avoid network failure because of one node failure. The protocol balances energy consumption of the network effectively, and extends the life cycle of the entire network.

Anomaly detection of privileged program behaviors is one of the most important means to ensure the system security. An alternative modeling method is proposed based on the BP neural network classifier, which builds upon the concept of the context dependency short sequences and the specially designed m-nearest algorithm. It is because that the neural network classifiers have the advantages of high generalization capability on unknown data, and the context dependency can more accurately determine the nature of local behaviors for the short sequences, behavior detection performance of program traces was evidently improved as compared with the previous modeling method.
