In order to meet the requirements of ultra-high network throughput, data rates and connectivity density emerging with the development of mobile Internet, IoT and 5G, ultra-dense networks (UDNs) have been envisioned as a key technology. By deploying a large number of lower-power small cells (SCs), including picocells, femtocells, relays, etc., in the coverage area of macro base stations (MBSs), the network capacity and spectrum efficiency in UDNs can be significantly improved, and thus the users’ QoE can be guaranteed. Compared with traditional cellular networks, the cellular links between the end users and the small/micro BSs in UDNs will be shortened to tens of meters or even shorter, while the ratio between the BSs and the active users will be higher (close to or even greater than 1). Moreover, with the aid of technologies such as dual-connectivity, coordinated multiple point (CoMP), massive multiple-input multiple-output (MIMO), cloud RAN, etc., an end user can simultaneously connect to multiple small/micro BSs except for the MBS. The scenarios where multiple small/micro BSs serve the same user at the same time become possible. The traditional network service mode shifts from BS-centric to user-centric, and the network throughput, spectrum efficiency and data rate will be further improved.

Moreover, with the explosive growth of smart mobile devices (SMDs) and the rapid development of new mobile Internet services, especially with the users’ continuous requirements for HD multimedia services such as HD pictures, video and live streaming, traditional cloud computing cannot meet users’ requirements for high throughput, ultra-low latency, ultra-high reliability and ultra-high connectivity density from the new applications. Mobile-edge computing (MEC), which can provide cloud services and computing capabilities at the radio access networks in close proximity to the SMDs, has been proposed as a solution. By offloading the SMDs’ computationally intensive tasks and the multimedia services from the cloud centre to the nearby edge servers, MEC can provide users with better QoE than local/cloud computing and a service environment with close distance, ultra-low latency, high bandwidth and real-time access to wireless network resources. The emergence of MEC has promoted the deep integration of traditional centralised cloud computing platforms and mobile telecommunication networks, thereby realising the “sinking” of mobile services and completing the transition of telecom operators from single “bit transmission pipelines” to information service platforms.

In ultra-dense mobile edge computing (UD-MEC) scenarios, considering the ultra-dense deployment of heterogeneous BSs and edge servers, the SMDs have to face the problems of frequent BS handovers and edge server reselection. In order to optimise key performance metrics such as processing delay, throughput, reliability, energy consumption, etc., and to protect the users’ privacy and data security during distributed edge caching among the edge servers, trying to combine the advantages of the two and make full use of network communication and computing resources still involves considerable challenges, especially in scenarios of multimedia processing.

This special issue aims at presenting prominent research outcomes and state-of-the-art advances in multimedia processing and security with ultra-dense mobile edge computing. Only technical papers describing previously unpublished, original, state-of-the-art research and not currently under review by a conference or another journal will be considered.
