This paper proposes an optical burst switched network architecture with distributed fairness control. Burst dropping at intermediate nodes is the weakness of the Optical Burst Switched network (OBS-n). To rectify this, the proposed architecture combines three technologies: ring structure, upstream prioritized switching (UPS), and distributed fairness control. By performing UPS on the ring, burs...

In this paper, we study short-term fairness in distributed, contention-based wireless medium access control (MAC) protocols. While most MAC protocols provide fairness among contending stations in the long term, they are not fair over shorter time scales. We rst demonstrate short-term unfairness of CSMA/CA using packet-level traces collected from an in-bulding wireless LAN network. We also analy...

Faster and larger transaction concerns in data communication are now an important field of study in academic and commercial research. As the number of users and the size of information to transmit increase, newer technologies should provide facilities to fulfil these needs. IEEE 802.11n is one of them. This high speed wireless standard is designed to guarantee faster delivery and better communi...

In this paper, a new protocol called MFQMAC is proposed, which has the following features. (i) It assures quality of service through service differentiation among different classes of traffics. (ii)It provides fairness among traffic flows of same priority class. It maintains fairness without decreasing the channel utilization and solves the unfairness problem between two communicating stations ...

BACKGROUND Social systems are dealing with the challenge of achieving fairness in the distribution of financial burden and protecting the risk of financial loss. The purpose of this paper is to present a trend analysis for the indicators related to fairness in healthcare's financial burden in rural and urban population of Iran during the eight years period of 2003 to 2010. METHODS We used the...

In this paper, a new subcarrier allocation algorithm is proposed for an OFDMA relay network with multicells. In the proposed algorithm, subcarriers are allocated to users and relays so as to maximize the overall sum of the achievable rate under fairness constraints. Fairness constraints are imposed on the minimum rate requirement of users and the maximum power of base stations and relays. Simul...

In order to be successful in multi-agent electronic negotiating environments, intelligent agents should be capable of adapting their negotiation strategies and tactics so that they can achieve an agreement with optimized profit. In this paper, some findings are going to be shown in which negotiating intelligent agents in electronic commerce start negotiating using a simplified standard protocol...

The concept of fairness index for self-authority servers in a large-scale network is introduced in this paper. The index quantifies the relative contributions of the servers to network routing, and can be used in network administration processes, such as negotiation of Multi-Lateral Peering Agreements. The fairness index concept leads naturally to the idea of an absolutely fair solution, which ...

This letter proposes a novel frequency channel blocking (FCB) scheme for millimeter-wave (MMW) entrance networks. In the FCB scheme, any frequency channel is determined to be blocked whether or not, based on not only the network throughput but also the newly defined fairness index. As the results, the FCB scheme yields better throughput and fairness performances with a little increase in comput...

This paper proposes two scheduling algorithms for subcarrier allocation of OFDM relay system, enhanced two-hop adaptive proportional fairness (E-THAPF) and user-number-dynamic two-hop adaptive proportional fairness (UND-THAPF), aiming to improve the performance of the traditional two-hop proportional fairness (THPF) scheduling algorithm. By modifying the priority of the two hops in THPF in an a...
