Special Issue Information

Dear Colleagues,

Since the introduction of world’s first consumer laptop in the 1980s, mobile computing has emerged as a hot topic in the information technology domain due to the noteworthy advantages it brings with respect to connectivity, computing, and mobility. With the advent of next-generation wireless systems, mobile computing has been proven to make significant contributions in the fields of emergency services, educational systems, healthcare, global positioning systems, and a lot more, since data can be transmitted and accessed by users anytime and anywhere via devices that do not require a physical link. Even though recent advances in the critical aspects of mobile computing such as communication, portability, and mobility are promising, it is also evident that more practical solutions are required to deal with the security facets so that the same can be accommodated well with the current technology trends. This Special Issue welcomes state-of-the-art and high-quality research works describing practical and theoretical solutions on mobile computing, wireless networks, and security.

Potential topics include but are not limited to:

  • Secure mobile computing and wireless network architectures and services;
  • Security, privacy, and trustworthiness in wireless and mobile computing systems;
  • Security-based energy aware wireless and mobile computing systems;
  • Algorithm or protocol design for secure computing systems;
  • Security applications of wireless networks and mobile computing;
  • Physical and pragmatic challenges of secure wireless and mobile computing systems;
  • Resource discovery, portability, and migration in secure mobile computing systems.

Our objective is to design triple-band implantable antennas with wide bandwidths and appropriate sizes for biomedical applications. The targeted design frequencies are 400 MHz, 2.4 GHz, and the new Wi-Fi band of 5.7 GHz. Three triple-band antennas with bandwidth improvements are presented to insure all-time data connection. The proposed triple-band implantable antennas benefit from combining long-distance data transfer at lower frequency bands and a higher effective bandwidth, and high-speed communications at higher frequency bands, which will have flexibility for a variety of applications. A comprehensive explanation of the design procedure to achieve multiple-band implantable antennas is provided. Furthermore, miniaturization techniques are utilized to design antennas in compact sizes suitable for biomedical applications. In this paper, three-layer structures including skin, fat, and muscle are used for the designs, then antennas are placed in the chest, neck, head, and hand of different human voxels to compare antennas’ performance. Additionally, normal and overweight human effects on antenna performance were compared. Antennas have 2 to 6 dBi directivity for telemetry usage, and they are designed to satisfy the absorption limit for the human body to keep the Specific Absorption Rate (SAR) averaged over 1 g of tissue less than 1.6 W/kg and over 10 g of tissue less than 2 W/kg, according to IEEE standard. The antennas include fractal, meandered, and comb types with sizes of 1.4 mm × 10 mm × 10 mm, 3.04 mm × 10 mm × 17.25 mm, and 1.4 mm × 12 mm × 12 mm, respectively. The designed antenna showed an impedance bandwidth of 53 MHz to 120 MHz, 90 MHz to 320 MHz, and 300 MHz to 1200 MHz at the three bands. The meandered antenna was selected for validation of simulations, and its S parameters were measured in the equivalent liquid phantom of body tissues. Full article
