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...
In this paper, the optimized routing or relay selection is discussed for the Cooperative Communication wireless networks. The whole network system performance or Quality of Service (QoS) can not be achieved without the optimal selection of the relay nodes. For this paper, the network performance is analyzed for m number of relays for n number of source nodes. The simulation results are measured by...
Anycast is a new type of communication service, and has been defined as a standard communication mode of the IPv6. With the more and more application need of anycast service, anycast routing problem (ARP) has recently become an important topic to study. An anycast routing algorithm based on genetic algorithm and particle swarm optimization is proposed in this paper. The algorithm overcomes the disadvantages...
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...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
