Vehicular networks or VANET announce as the communication networks of the future, where the mobility is the main idea. These networks should be able to interconnect vehicles. The optimal goal is that these networks will contribute to safer roads and more effective in the future by providing timely information to drivers and concerned authorities. They are therefore vulnerable to many types of attacks among them the black hole attack. In this attack, a malicious node disseminates spurious replies for any route discovery in order to monopolize all data communication and deteriorate network performance. Many studies have focused on detecting and isolating malicious nodes in VANET. In this paper, the authors present two mechanisms to detect this attack. The main goal is detecting as well as bypass cooperative black hole attack. The authors' approaches have been evaluated by the detailed simulation study with NS2 and the simulation results shows an improvement of protocol performance.

The smart grid that the next-generation electric power system is studied intensively as a promising solution for energy crisis. One important feature of the smart grid is the integration of high-speed, reliable and secure data communication networks to manage the complex power systems effectively and intelligently. The goal of smart grid is to achieve the security of operation, economic efficient and environmental friendly. To achieve this goal, we proposed a fine-grained access control model for smart grid. In order to improve the security of smart grid, an access-trust-degree algorithm is proposed to evaluate the reliability of the user who want to access to the smart grid.

The mobile Internet is a fast-growing technology that provides access to the traditional stationary (fixed-line) Internet from devices connected to mobile communication networks. It is predicted that the convergence between mobile networks and the fixed-line Internet will be a core feature in the next generation network architecture, achieving fast ‘anywhere’ Internet access and global mobility management. Applying a case study approach, this paper reviews the New Zealand mobile Internet market mix, competition, and mobile service provision. The key mobile Internet deployment requirements are determined and analyzed in order to identify a set of mobile Internet critical success factors and to investigate the impact of the shift from fixed-line to mobile and wireless Internet data communication infrastructure.

The way of life has changed with the introduction of information and communication technologies (ICT) in every one’s day to day activities and the business. As ICT technologies are constantly evolving, many people attribute the success of enterprises to the ways they deploy and take advantage of new technologies, not only to make their operations more efficient but most importantly to refine and adopt new effective and adaptive business models. Since the advent of the Internet and the very first Internet service providers (ISP) in operation, the traditional ISP market has been in constant evolution due to the gradual globalisation and commoditisation of ISP services. Deregulation and ICT policies have fostered competition (e.g., unbundling of the local loop and so forth) as well. The Internet is as an important channel of interaction inside and/or outside enterprises. The essence of the Internet is conducting business and running of business processes over data communication networks based on nonproprietary standards (Porter, 2001). The World Wide Web as a portal represents a major electronic business (e-business) platform accessed through communication channels provisioned by network and service providers (such as ISDN, DSL, WLAN, UMTS, etc.). There are many challenging aspects of the e-Business that must be considered for a sustainable business of an ISP (Petrie et al., 2004).
