Network Coding is a new field that aims at, notably increasing the throughput in a network. ROCX [1] is an algorithm that makes routing with the awareness of network coding. However, its major limitation is that it does not take into account the bandwidth limitation and the interference impact. If the interference is not considered in a wireless network, a flow requiring a certain bandwidth might...
Concerning event-driven wireless sensor network scenario where the traffic has burst-bulk characteristic, an intra-flow network coding based opportunistic multipath routing protocol called Code Paths was proposed. A routing metric taking delay and congestion factors into account has been defined and implemented, which is used to establish gradient field from nodes to sink. When an event occurs in...
Real-time multimedia transport has stringent QoS requirements, such as bandwidth, delay, jitter, and loss ratio. Wireless sensor networks are useful for streaming multimedia data in infrastructure-free and hazardous environments. However, these networks are composed of nodes with constrained bandwidth and energy. In QoS routing for wired networks, multipath routing is widely used. Some existing ad...
