The sixth-generation (6G) network will shift its focus to supporting everything including various machine-type devices (MTDs) in an everyone-centric manner. To ubiquitously cover the MTDs working in rural and disastrous areas, satellite communications become indispensable, while mobile edge computing (MEC) also plays an increasingly crucial role. T...

... integrated satellite-MEC network is envisioned to support various MTDs in an everyone-centric manner [1]. As shown in Fig. 1(a), we summarize typical use cases in the ...
Context 2
... is an important but challenging problem to efficiently utilize the limited network resources to meet the wide-area and sparse service demands. To handle this problem, we provide a novel systematic perspective inspired by the protein structure, as shown in Fig. 1. Specifically, we propose three minimal integrating structures and discuss their corresponding characteristics and problems based on the location of MEC server. A more complex integrated satellite-MEC network can be considered as an orchestration of these structures. By figuring out the minimal integrating structures, as well as their ...

... shown in Fig. 1(b), this minimal integrating structure consists of an AP equipped with an MEC server, a satellite, a gateway and multiple MTDs. The AP can be a UAV or a high altitude platform (HAP). With MEC deployment, the AP provides local computation services for MTDs. Due to the limitations of APs in terms of size and energy, the central processing ...

... minimal integrating structure is composed of a satellite equipped with an MEC server, a gateway and multiple MTDs, as shown in Fig. 1(c). The MTDs' computation tasks can be directly executed at the satellite or further uploaded for cloud computing. The satellite is highly limited in terms of size, weight and energy supply, which places stringent restrictions on the CPU capability of the on-board MEC server. There are several derivatives from this minimal structure. For ...

... shown in Fig. 1(d), this minimal integrating structure consists of a satellite, a gateway equipped with an MEC server and multiple MTDs. MTDs offload their computation tasks to the gateway through the satellite relay. The computation tasks are executed in the gateway server or they are transmitted to the remote cloud. It should be noted that the MEC ...
