Development of auto industry leads to parking difficulty and traffic jam in the city, which decreases operating efficiency of the city and happiness of people. Under the circumstances, parking space is planned on both sides of roads, by which the traffic jam is relieved to a certain extent. But some problem exists in management of the parking space as follows: Firstly, the management cost is high such as Human Resources investment. Secondly, rate of received fees (about 30 percent) is low because many car owners don’t pay parking fees consciously. For the above problems, in this paper, the road intelligent parking request is firstly analyzed, and then an intelligent management and fee collecting solution for the road parking based on IoT is put forward. Besides, a management and control platform of road intelligent parking is designed. Finally key technologies for this system are analyzed. The purpose is to realize intelligent management, lower management cost, and higher fee collecting rate for the road parking.

Abstract:In this paper, we study the throughput capacity of wireless networks considering the selfish feature of interaction between nodes. In our proposed network model, each node has a probability of cooperating to relay transmission. According to the extent of selfishness, we, by the application of percolation theory, construct a series of highways crossing the network. The transmission strategy is then divided into three consecutive phases. Comparing the rate in each phase, we find the bottleneck of rate is always in the highway phase. Finally, the result reveals that the node's selfishness degrades the throughput with a factor of square root of the cooperative probability, whereas the node density has trivial impact on the throughput.

Based on the principle and characteristics of cloud computing, we put forward the detailed introduction of the constitution and function of cloud information resource flow architecture. Therefore, the problems of network source information management, supervisory control, exploitation and utilization can be solved.

As the second line of defense, intrusion detection is the necessary means of getting the high survivability. Intrusion detection technology and its classification is described in this article. And based on the features of Ad Hoc network, the existing new network intrusion detection technology and its characteristics suitable for Ad Hoc network are summarized.
