A spectrum allocation scheme for DASH multicast service over wireless network

Dynamic Adaptive Streaming over HTTP (DASH) is a prospective video transmission technique. It can select appropriate bitrates for users according to channel conditions and capacities of user equipments. Multicast of DASH is a promising but challenging way to improve spectrum efficiency. It has not been sufficiently researched. However, in this paper, we focus on investigating a spectrum allocation scheme for DASH multicast service. To this end an optimization problem is formulated and a multicast spectrum assignment algorithm called DASH Multicast Fairness (DMF) is proposed. Simulation results show that the proposed scheduling algorithm outperforms others in multicast scenario.
