This study proposes a novel WDM EPON system based upon an AWG, in which multiple wavelengths are established in both the upstream and the downstream fibers. The use of the AWG enab...
Abstract—Hash tables are used in many networking applications, such as lookup and packet classification. But the issue of collisions resolution makes their use slow and not suit...
Abstract—Cooperative diversity is a useful technique to increase reliability and throughput of wireless networks. To analyze the performance gain from cooperative diversity, outa...

— This paper investigates the role of providers’ market shares for consumers and websites on interconnection settlements between networks. We proposed to differentiate traffic ...
— In this paper, we study the optimal transceiver structure for achieving sum-rate capacity of a parallel Gaussian symmetric interference channel. Specifically, we derive a set ...
— This paper analyzes the ergodic mutual information of OFDMA cooperative relay networks when the Channel State Information (CSI) imperfection is considered at resource allocatio...
Abstract— In this paper, we evaluate the performance improvement in an Orthogonal Frequency-Division Multiple Access (OFDMA) uplink achievable with cooperative relaying in the pr...
