Maximum-Lifetime Coding Subgraph for Multicast Traffic in Wireless Sensor Networks (original) (raw)
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
Abstract
It has been shown that network coding can lead to significant improvement in network capacity and reduction in power consumption for multicast traffic in wireless networks. In this paper, we study the problem of supporting multicast in wireless sensor networks. The objective is to jointly maximize the network lifetime and minimize the number of packets undergoing network coding. We formulate
