In this paper, we evaluate the capacity of multi-channel, multi-hop ad hoc network. In particular, we show the performance of multi-hop ad hoc network with single channel IEEE 802.11 MAC utilizing different topologies. We also introduce scaling laws of throughputs for large-scale ad hoc networks and propose the theoretical guaranteed throughput bounds for multi-channel grid topology systems. We...

Multi-Channel Access has the potential to solve the throughput and scalability issues that mar the performance of 802.11 mesh and adhoc networks. It allows multiple simultaneous transmissions in a radio neighborhood thereby increasing network throughput and scalability. In spite of this potential, it is limited to simulation studies and its implementation on hardware is rare. In this demo, we d...

In this paper a multi-channel MAC protocol with dynamic channel allocation (MMAC-DCA) in CDMA Ad Hoc networks is proposed. Under MMAC-DCA, the service sub-channels are dynamically allocated by the RTS/CTS dialogue on the common sub-channel, only when a node has a packet to transmit. In addition, a Markov mode is presented to analyze the performance of MMAC-DCA. key words: Ad Hoc networks, dynam...

This paper analyzes performance and throughput of an adaptive bit allocation and variable rate algorithm depending on channel state information (CSI) and a transmit power in a multi-user OFDM transmission. The purpose of the presented multi-rate OFDM system using adaptive modulation is to increase bandwidth efficiency by controlling constellation size and to adapt proper service for each user a...

The purpose of this paper is to examine and compare multi-channel compositional practices in the scope of electroacoustic music and discuss arising issues regarding compositional methodology, rationale, performance and dissemination of multi-channel works with examples drawn from the author’s compositional output. The paper describes principal theories of musical space and draws parallels betwe...

In Wireless Mesh Networks (WMN), a channel assignment has to balance the objectives of maintaining connectivity and increasing the aggregate bandwidth. The main aim of the channel assignment algorithm is to assign the channels to the network interfaces, from the given expected load on each virtual link. From the existing work done so far, we can examine that there is no combined solution of mul...
