Information interaction system plays an important role in establishing a real-time and high-efficient traffic management platform in Intelligent Transportation System (ITS) applications. However, the present transmission technology still exists some defects in satisfying with the real-time performance of users data demand in Vehicle-to-Vehicle (V2V) communication. In order to solve this problem, this...
This paper introduces a new type of consensus protocol in undirected networks, which leads to a corresponding neutral multi-agent system. Such a protocol not only comprises the usual linear protocol as a particular case, but also allows a less conservative estimate on the upper bound of time delay. By decoupling the neutral multi-agent system in terms of the eigenvalues of the Laplacian matrix, necessary...
In VANET, vehicles moving on the highway usually form clusters, and the wireless communications between vehicles are generally conducted by cluster heads. In most cluster-based protocols, however, the cluster head selection carried out through inter-cluster communications has some limitations, e.g., large communication and computation cost, quite complex algorithms, requirement of additional devices...
Vehicle traffic congestion has become a serious urban phenomenon in recent years, resulting in a large number of negative effects both on economy and ecology. Thus, finding a way to detect traffic congestion is a highly urgent problem to be solved by scientists and politicians throughout the world. One new promising approach is the usage of vehicular ad-hoc network (VANET). In this paper, we study...
The Artificial Fish-swarm Algorithm (AFA) is an intelligent population-based optimization algorithm inspired by the behaviors of fish swarm. Unfortunately, it sometimes fails to maintain an appropriate balance between exploration and exploitation, and has a drawback of blind search. In this paper, a novel cultured AFA with the crossover operator, namely CAFAC, is proposed to enhance its optimization...
The traditional loss based congestion control protocol is not suitable for media streaming. because the loss based congestion control can not limit the Round Trip Time and it is also too sensitive about one side congestion, while most ADSL links which often have an asymmetric bandwidth. So in this paper, we present a novel One-Way-Trip Time based congestion control protocol, and prove its performance...
In cognitive radio networks, cooperative spectrum sensing is employed to detect the presence of primary user quickly. In this paper, we study the sensing performance of a cognitive user U1 by allowing another cognitive radio user U2 to act as its relay (cooperation). We take the average power rather than the instantaneous power as the decision statistic, so, we can use multiple signal samples in each...
In the design of modern vehicles, CAN-bus network has been applied for the information exchange among the ECUs of the vehicle. The CAN communication network for vehicle management system (VMS) is designed based on XC164CS microcontroller in the paper. The characteristics and construction of Twin CAN module of XC164CS were introduced. The principle of time triggered controller area network (TTCAN)...
Botnet has recently been identified as one of the most important security threats of the Internet. So we should study the new technology which may be used by botmaster in the near future. In this paper we predict the new feature of the next generation botnet and present the design of an advanced P2P botnet basing on our discussion.
