Network Coding is a recent technique that has many advantages such as reducing the bandwidth consumption and increasing the throughput. IROCX [1] is a routing algorithm that applies Network Coding while considering the interference impact. However, it assumes a constant transmission power. We extend IROCX by allowing the nodes to transmit with several power levels. Our approach, TC-IROCX (Topology...
Network coding is known to be a promising technology to increase the bandwidth capacity in wireless networks. To our best knowledge, there is limited work on studying the available bandwidth for a given path with network coding. This paper presents a new method to estimate the available bandwidth of a path that considers network coding and wireless interference simultaneously. We show that our estimated...
This paper discusses the problem of computing the maximum available bandwidth of a given path in TDMA-based network with network coding, which is a fundamental issue for supporting QoS with bandwidth requirement in wireless networks. We present a new path bandwidth computation mechanism considering physical-layer network coding. To our best knowledge, our work is the first proposal on assigning time...
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...
Three applications in wireless networks where model-free stochastic learning is applicable, are discussed. The learning based optimization problems are formulated and simulation results are presented. Some open issues are also discussed.
In this work we investigate the effects of multiple access interference (MAI) and polarization mode dispersion (PMD) in optical code division multiplexing (OCDM) lightpaths. These paths are determined by the data encoding with non-coherent optical orthogonal codes (OOC), using a sequence inversion keying (SIK) optical correlator system. Our results show the impact of MAI effects and PMD constraint...
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...
