We present Duo-MAC, an asynchronous cascading wake-up scheduled MAC protocol for heterogeneous traffic forwarding in low-power wireless networks. Duo-MAC deals with energy-delay minimization problem and copes with transmission latency encountered by Today's duty-cycled protocols when forwarding heterogeneous traffic types. It switches, according to the energy and delay requirements, between Low Duty...
Multicast services are used in emerging multimedia applications based on Quality of Service (QoS) development of multimedia group application and the construction of multicast routing tree is significant. Upper bound on the delay between sender and receiver is one of the common QoS constraints. Delay-constrained routing protocols are used to find paths subject to the delay constraint while efficiently...
In the context of networks providing QoS guarantees, the end-to-end delay experienced by a packet is an important parameter. In this paper, we show that network coding can be used to decrease worst case end-to-end bounds when compared to a classical routing strategy. This result can be explained by the fact that network coding can cope with congestion better that classical routing due to its property...
