Energy-efficient proactive caching with multipath routing

The ever-continuing explosive growth of on-demand content distribution has imposed great pressure on mobile/wireless network infrastructures. To ease congestion in the and to increase perceived user experience, caching popular closer end-users can play a significant role as such this issue received attention over last few years. Additionally, energy saving is treated fundamental requirement design next-generation mobile networks. However, there been little overlapping area between especially when considering multipath routing. end, paper proposes an energy-efficient with routing support. proposed scheme provides joint anchoring into set potential nodes optimized support whilst ensuring balance transmission cost. model also considers different delivery modes, multicast unicast . Two separated Integer-Linear Programming (ILP) models are formulated for each mode. tackle curse dimensionality we then provide greedy simulated annealing algorithm , which not only reduces time complexity but competitive performance. A wide numerical investigations reveal that consumption up 75% compared other widely used approaches under premise resource limitation. Sensitivity analysis parameters meticulously discussed paper.
