Abstract:
Content distribution is a key technology to
achieve data sharing among mobile terminals in Mobile
Peer to Peer (MP2P) networks. Nevertheless, in the
dynamic/mobile environment, the poor computing ability
and storage capability of a single node make it difficult to
share the content among nodes. In order to enhance the
capability of the mobile terminals and improve the
efficiency of content distribution, a cloud-assisted
architecture to offload the heavy computation load from
the mobile nodes to the cloud was put forward.
Furthermore, a Multi-Tree Structure of Internal Node
Disjoint (MTSIND) data transfer topology was proposed,
in which their internal nodes are disjoint, thus each node
can take part in the content delivery tasks. Finally, an
exclusive-OR (XOR) network coding method based on
vertex coloring problem was established to reduce the
number of transmissions and power consumption.
Simulation and numerical results were provided to support
the analyses and results. Results show that the content
distribution mechanism can reduce the total number of
the data packets and the energy consumption. The study
proves that the research of content distribution mechanism
on MP2P has a great significance on reducing the number
of data transmissions, lowering the power consumption
of terminals and increasing the resource utilization of mobiloe nodes
