The energy consumption in Wireless Multimedia Sensor Networks (WMSNs) is much greater than that in traditional wireless sensor networks. Thus, it is a huge challenge to remain the perpetual operation for WMSN. In this paper, the authors propose a new heterogeneous energy supply model for WMSN through the coexistence of renewable energy and electricity grid. They address to cross-layer optimization for the multiple multicast with distributed source coding and intra-session network coding in Heterogeneous Powered Wireless Multimedia Sensor Networks (HPWMSNs) with correlated sources.
