Special Issue Information

Dear Colleagues,

The long-term vision of mobile communication and computing is to transform the network into an energy-saving distributed computer that can be flexibly and dynamically created and moved to meet users' needs. To make this vision a reality, it must continuously improve innovative service management and network communication technologies. However, the main challenge facing these mobile computing technologies is protecting networks and system assets (i.e., services, data, and network infrastructure) from potential network security risks brought about by unprecedented hacker threats.

This Special Issue aims to gather the latest research results concerning security in mobile communication and computing. Researchers, experts, and scholars are encouraged to present their contributions and research directions on this issue.

Topics of interest include, but are not limited to:

  • Security, privacy, and trust in mobile communications and computing;
  • Security, privacy, and trust in 5G/beyond 5G and 6G;
  • Security, privacy, and trust in VANET;
  • Security, privacy, and trust in the IoT;
  • Artificial intelligence/machine learning techniques in security for mobile communications and computing;
  • Security, privacy, and trust of digital twins;
  • Security, privacy, and trust in edge computing.

Low-orbit micro-satellite technology has developed rapidly in recent years due to its advantages of low time delay, low cost and short research period. However, among the existing inter-satellite routing algorithms, the classical flooding and greedy algorithms and their derivatives also have some limitations. The path delay calculated by the flooding algorithm is small but the calculation is large, while the greedy algorithm is the opposite. In this paper, a balanced inter-satellite routing algorithm based on partition routing is proposed. This paper presents the simulation experiments for the following indexes of the classic inter-satellite routing algorithms and the balanced partition routing algorithm: computation complexity, single-node computation pressure, routing path delay, path delay variance (data in Topo table satisfy μ =5, σ2=10). The results reveal that the balanced partition routing algorithm achieves better performance. In this paper, two optimization directions of the balanced partition routing algorithm are simulated under conditions that the data in the Topo table satisfy μ =5, σ2= 6, σ2=10 and σ2=15, respectively, when comparing their performance indicators. The experiments show that these two optimization methods can be adapted to various application scenarios and can further reduce the hardware cost of satellite nodes. Full article

Wireless Sensor Networks (WSNs) are networks of small devices with limited resources which are able to collect different information for a variety of purposes. Energy and security play a key role in these networks and MAC aspects are fundamental in their management. The classical security approaches are not suitable in WSNs given the limited resources of the nodes, which subsequently require lightweight cryptography mechanisms in order to achieve high security levels. In this paper, a security analysis is provided comparing BMAC and LMAC protocols, in order to determine, using AES, RSA, and elliptic curve techniques, the protocol with the best trade-off in terms of received packets and energy consumption.
