A wireless ad hoc network is a decentralized type of wireless network. It is a type of temporary computer-to-computer connection. It is a spontaneous network which includes mobile ad-hoc networks (MANET), vehicular ad-hoc networks (VANET) and Flying ad-hoc networks (FANET). A MANET is a network that has many free or autonomous nodes often composed of mobile devices that can operate without strict top-down network administration [1]. A VANET is a sub form of MANET. It is a technology that uses vehicles as nodes in a network to create a mobile network. FANET is an ad-hoc network of flying nodes. They can fly independently or can be operated distantly. This paper discusses the characteristics of these three ad-hoc networks.

Esports is a rapidly growing industry. However, the unidentifiable governance structure of the industry has contributed to a number of integrity-eroding activities. By exploring esports stakeholder dynamics, this paper answers the question, “Is the esports governance model sustainable?” Data were sourced from documentation, focus groups (N = 3) and semi-structured interviews (N = 6). Thematic analysis was conducted using Nvivo. The findings suggest that (1) the current esports governance framework features some attributes of the “lead organisation-governed network”, with the power residing mainly in game publishers; (2) the rising power of other stakeholders in the network seeking to address integrity issues has caused fragmentation of the esports governance framework; (3) esports governance is evolving towards a network administration organisation (NAO) model. Such evolution has a few challenges—most notably, the compliance of game publishers. Given the social impact of the integrity issues, governments should play a main role in facilitating a NAO model.

Now IPv6 has been considered as one of the core standards for the next generation Internet Protocol. The network behavior and attack are quite different in IPv6 environment because of the difference between IPv4 and IPv6 Protocol. The increasing expansion of network scale and the exponential growth of network application are urging the research that a firewall for IPv6 environment should be deployed and implemented. This paper studies Netfilter architecture in detail, and explores the Shorewall6 firewall source codes. Furthermore, an IPv6 firewall based on Netfilter is implemented by modifying the Shorewall6 firewall source codes and adding some iptables rules according to the application environment. The implemented IPv6 firewall based on Netfilter makes it convenient for administrators to simplify IPv6 network administration tasks and has furthered the development of IPv6 firewall to some extent.
