Low bandwidth.
Bandwidth is one of the big issues
in MCC because the radio resource for wireless
networks is much scarce as compared with the
traditional wired networks.
Jin and Kwok [63] proposes a solution to share
the limited bandwidth among mobile users who are
located in the same area (e.g., a workplace, a station,
and a stadium) and involved in the same content
(e.g., a video file). The authors model the interaction
among the users as a coalitional game. For exam-
ple, the users form a coalition where each member
is responsible for a part of video files (e.g., sounds,
images, and captions) and transmits/exchanges it
to other coalition members. This results in the
improvement of the video quality. However, the pro-
posed solution is only applied in the case when the
users in a certain area are interested in the same con-
tents. Also, it does not consider a distribution policy
(e.g., who receives how much and which part of con-
tents) which leads to a lack of fairness about each
user’s contribution to a coalition
