Delay Tolerant Networks (DTN) is a kind of sparse Ad Hoc networks in which no contemporaneous path exists between any two nodes most of the time. Multicasting in DTN is a desirable feature for applications where some form of group communication is in demand. In this paper, we propose a multicast protocol for DTN: ECAM (Epidemic-based Controlled Flooding and Adaptive Multicast for Delay Tolerant Networks)...
Energy conservation is a critical issue in wireless ad hoc networks, as usually nodes are powered by batteries only. This paper proposes a cross-layer design of energy-aware multicast ad hoc on-demand distance vector (CEMAODV) routing protocol. At one hand it adopts cross-layer mechanism and energy-aware metric to modify AODV routing protocol to reduce the energy consumption of the route to construct...
