IEEE 802.11 Distributed Coordination Function (DCF) guarantees fair transmission opportunity to stations. Channel occupation of low rate stations in IEEE 802.11 Wireless Local Area Network (WLAN) causes the performance anomaly resulting in the degradation of overall network throughput. Using cooperative communications between a high rate station and a low rate station, performance anomaly can b...

Abstract CO 2 methanation can be a key technology for realizing sustainable society. CH 4 is used as an energy carrier and raw material chemical products, thereby contributing to the reduction of emissions. Methanation with plasma catalysis lowers process temperature, which improve throughput stability. In this study, we investigated effect gas flow rate discharge volume on methanation, using l...

In this paper, we propose a heuristic scheduling scheme, named hybrid resource allocation scheme that can reduce the time complexity of scheduling scheme and improve the efficiency of resource utilization while minimizing interference. We first focus on the two-hop relaying scenario, since this scenario has the largest throughput gain, and then explore an extension of the proposed hybrid scheme...

Designing mobiles to harvest ambient energy such as kinetic activities or electromagnetic radiation will enable wireless networks to be self sustaining besides alleviating global warming. In this paper, the spatial throughput of a mobile ad hoc network powered by energy harvesting is analyzed using a stochastic-geometry model. In this model, transmitters are distributed as a Poisson point proce...

In order to improve the total system throughput by analyzing the resource allocation problems in backhaul links and access links of base stations in ultra-dense network (UDN), a proportional fair resource allocation (PFRA) algorithm was designed for the wireless hybrid hierarchical backhaul network in this paper. First, the base stations were stratified and the frame structure of each base stat...

The aim of this study was the increasing of leachate quality using integrated membrane bioreactor (MBR). The reactor was fed with treated leachate with overall 70-1360 mg/l chemical oxygen demand (COD). The analysis of COD, biochemical oxygen demand (BOD5), total suspended solids (TSS), and total dissolved solids (TDS) were performed in feed and filtrate, whenever the system reached steady stat...

The network nodes that are connected by wireless data connections called as wireless networks. The devices are connected via wireless link to communicate with each other. In wireless networks, it is very difficult to maintain the trade-off between throughput and delay. This paper proposes a new joint scheduling and congestion control algorithm for multihop wireless networks with dynamic route f...

We consider a collision channel, shared by a finite number of self-interested users with heterogenous throughput demands. It is assumed that each user transmits with a fixed probability at each time slot, and the transmission is successful if no other user transmits simultaneously. Each user is interested in adjusting its transmission rate so that its throughput demand is met. When throughput r...
