- Equalization attacks against OFDM: analysis and countermeasures
Chowdhury Shahriar, T. Charles Clancy and Robert W. McGwier
Article first published online: 27 NOV 2015 | DOI: 10.1002/wcm.2648
Conventional orthogonal frequency division multiplexing (OFDM)-based communications systems use known subcarriers (called pilot tones) to estimate the channel frequency response and perform equalization. This paper presents a number of power-efficient jamming attacks that target OFDM equalization process and disrupts communication. This paper also proposes countermeasures for such jamming attacks by randomizing pilot tone locations.

Article first published online: 26 NOV 2015 | DOI: 10.1002/wcm.2645
In this work, unified performance analysis of various transmit, receive and hybrid diversity techniques is studied over generalised-K composite fading channels. Exact and asymptotic performance expressions are derived. We show that the diversity orders of the investigated scenarios are the minimum of the diversity order of the system for only small-scale fading channel case and the shadowing parameter, and limited by the shadowing effect especially in heavy shadowing case.
- QoE- and energy-efficient resource optimization in OFDMA networks with bidirectional relaying
Xiaolin Ma, Fangmin Li, Jacek Ilow and Zhizhang Chen
Article first published online: 26 NOV 2015 | DOI: 10.1002/wcm.2644
The resource optimization considering QoE and energy efficiency (QEE) tradeoff in bidirectional OFDMA relaying networks with dynamic network coding is investigated. Such QEE is proved to be quasi-concave on QoE, making the formulated QEE optimization problem being a quasi-concave optimization, which can be transformed into a sequence of feasibility problems that are governed by a bisection method. An efficient resource allocation strategy is then developed to obtain the optimal QEE point, and simulations validate its performance and the theoretical findings.
- Distributed mobility management in named data networking

Article first published online: 25 NOV 2015 | DOI: 10.1002/wcm.2652
In this paper, the authors propose a novel mobility management scheme to support fast handover for both the mobile receiver and publisher in Named Data Networking (NDN). This proposal uses the hierarchical names to identify the target access router (AR), and then the network-based branching node selection is adopted for the distributed mobility management. The analytical results demonstrate that the proposed scheme inherits the scalability and efficiency of NDN in the mobile Internet.
- Theoretical analysis on caching effects in urban vehicular ad hoc networks

Article first published online: 25 NOV 2015 | DOI: 10.1002/wcm.2651
This paper presents a theoretical analysis on the caching effects in urban vehicular ad hoc network scenarios. Quantitative relationship is found among the caching performance metric and network parameters including vehicle density and transmission range. And the vehicle mobility is also considered to predict the future caching effects. Simulations show that our theoretical model matches well with the simulated reality in different scenario settings.
