The throughput enhancement of Space-Time Spreading (STS)-based Multicarrier Direct Sequence Code Division Multiple Access (MC DS-CDMA) system is investigated in this paper. Variable Spreading Factor (VSF) is utilized to improve the data throughput of the system. In this contribution, an analytical approach is proposed to compute a new expression for the Bit Error Rate (BER) performance of t...

increasing the number of cores integrated on a chip and the problems of system on chips caused to emerge networks on chips. nocs have features such as scalability and high performance. nocs architecture provides communication infrastructure and in this way, the blocks were produced that their communication with each other made noc. due to increasing number of cores, the placement of the cores i...

. The absence of centralized administration, multi-hop transmission, and the nature of wireless channels pose many challenging research area in Mobile Ad hoc NETworks (MANETs). In this paper, a collision avoidance Medium Access Control (MAC) protocol was used for the modeling and analysis of multi-hop wireless ad hoc network, in which RTS/CTS/DATA/ACK handshake and Exponential Increase Exponent...

Packet Classification is the enabling function for many Internet functions like QoS and Security. In this paper we propose a Classification engine architecture which exploits parallelism to increase throughput. The architecture also make use of the Temporal locality observed in Internet traffic positively by employing Popular Rule Caching mechanism to increase the classification throughput. We ...

Wireless metropolitan grid promises to offer various broadband services to citizens anywhere with low cost. The problem of throughput and scalability are still critical challenges for the success. In this paper, we propose and evaluate scalable backbone architecture which employs super nodes with asymmetric capability to reduce the hop count as well as increase the scalability. Multi-channel mu...
