Table 6 CDN challenges in MSN
From: Content distribution and protocol design issue for mobile social networks: a survey
Method | Challenges | Contributions |
|---|---|---|
[96] | Startup latency (QoS) | Proposed for the purpose of downloading the initial packets of a content item that is from the closed CDN nodes geographically |
[97] | Startup latency (QoS) | Proposed an efficient technique for the buffer management which distribute the client’s buffer among the ON region |
[98] | Startup latency (QoS) | Proposed for the division of the playback of the buffer into the CDN region, an emergency region along with a peer region. The peer region is transformed to an emergency region in the case of the user failure to download the required content from neighboring peers before the playback deadline |
[99] | Startup latency (QoS) | Proposed for P2P resources and scheduling algorithm for the purpose of achieving fewer startup delays |
[100] | Startup latency (QoS) | Proposed the chunk pre-fetching based algorithm build on social relationships along with the physical position of peers in online social networks (OSNs) |
[101] | Playback latency (QoS) | Proposed an algorithm called location-based peer selection by the induction of a CAN .method that clusters peers that is based on the delays and the channel streaming they are watching |
[102] | Inaccessibility | Proposed an architecture known as CDN centralized hybrid architecture that is based on BitTorrent to solve the problems of firewalls |
[103] | Authentication | A proposed a scheme for peer authorization with the help of a network coding scheme for the purpose of preventing illegal distribution of the content within the network |
[104] | Copyright | Proposed architecture called centralized PA-CDN, such architecture used tracker server to authorize the users |
