human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "on optimization of network coded scalable multimedia service multicasting"):
  Abstract: In the near future, the delivery of multimedia multicast services over next-generation networks is likely to become one of the main pillars of future cellular networks. In this extended abstract, we address the issue of efficiently multicasting layered video services by defining a novel optimization paradigm that is based on an Unequal Error Protection implementation of Random Linear Network Coding, and aims to ensure target service coverages by using a limited amount of radio resources.

Includes members:
  Member "resource allocation frameworks for network coded layered multimedia multicast services":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "resource allocation for loss tolerant video streaming in embms")
  Member "optimized network coded scalable video multicasting over embms networks":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "resource allocation for loss tolerant video streaming in embms")
