In this paper, the authors propose a new multicast subgraph construction algorithm and a Distributed Source Coding-based Multicast (DSCM) protocol for multihop wireless networks. The DSCM emphasize reliability, rate optimality, and energy efficiency. Both algorithms are based on local knowledge of the network. DSCM uses rateless error correcting codes to provide reliability and rate optimality, and distributed source coding to ensure the energy efficiency. They compared the scheme to energy-efficient methods such as Network Coding (NC) and Multicast Incremental Power (MIP).
