Wireless Sensor Network (WSN) is an independent device that comprises a discrete collection of Nodes (SN) to sense environmental positions, monitoring, and information. Due limited energy resources available at SN, the primary issue present energy-efficient framework conserve while constructing route path along with each sensor node. However, many techniques focused drastically on harvesting re...

In wireless powered communication networks (WPCNs), it is essential to research energy efficiency fairness in order to evaluate the balance of nodes for receiving information and harvesting energy. In this paper, we propose an efficient iterative algorithm for optimal energy efficiency proportional fairness in WPCN. The main idea is to use stochastic geometry to derive the mean proportionally f...

We review two areas of recent research linking proportional fairness with product form networks. The areas concern, respectively, the heavy traffic and the large deviations limiting regimes for the stationary distribution of a flow model, where the flow model is a stochastic process representing the randomly varying number of document transfers present in a network sharing capacity according to...

In this paper, we study resource allocation problem in orthogonal frequency division multiple access multiple-input multiple-output (OFDMA-MIMO) relay systems and formulate the optimal instantaneous resource allocation problem including subcarrier assignment, relay selection and power allocation to maximize system capacity. Based on the assumption that the availability of perfect channel state ...

This paper considers proportional fairness amongst ACs in an EDCA WLAN for provision of distinct QoS requirements and priority parameters. A detailed theoretical analysis is provided to derive the optimal station attempt probability which leads to a proportional fair allocation of station throughputs. The desirable fairness can be achieved using a centralised adaptive control approach. This app...

In this paper, we suggested an algorithm to guarantee QoS (Quality of Service) and provide priority for users in 1xEV-DO systems. On forward link, a selected user is served in a TDM fashion with full base station power. The transmission rate depends on the forward link channel quality of each access terminal, which is reported by DRC channel. 1xEV-DO systems adopted an efficient scheduling algo...

Existing wireless MAC standards are known to have fairness problems. In this paper, we ask a more fundamental question: should fairness be a property of medium access, or in other words, are we placing the blame on the right place? We argue that fairness is a property of applications and must be implemented by applications. Medium access control should simply provide mechanisms for application-...
