Site diversity causes unfairness in packet reception that depends on the location of the mobile stations in the uplink of CDMA cellular packet communication systems. This paper proposes an adaptive transmit permission probability control scheme that reduces this unfairness in CDMA cellular slottedALOHA systems with site diversity. The proposed scheme adaptively controls the transmit permission ...

This paper presents a measurement study of TCP performance at an operational WiFi deployment. After presenting the network topology and the tools used to generate and analyze traffic, we examine the throughput performance of competing TCP connections. We investigate how throughput is divided among the participating wireless hosts with respect to signal strength, traffic direction and use of the...

Serotonin (5-HT) has long been implicated in social behavior and impulsivity, but the mechanisms through which it modulates self-control remain unclear. We observed the effects of manipulating 5-HT function on behavior in the ultimatum game, where players must decide whether to accept or reject fair or unfair monetary offers from another player. Participants with depleted 5-HT levels rejected a...

Short-lived TCP connections, which transmit small-sized data, suffer from significant low throughput compared with long-lived TCP connections, which transmit large-sized data, because of the inherent nature of the ACK-based window flow control of TCP. In this paper, we focus on the unfairness problem caused by transmitting differently sized data. We first confirm the unfairness property through...

We report an experiment on the covered response ultimatum game, in which the proposer is not informed about the responder’s reaction to an unequal offer. In this game, no education of proposers is possible. A control experiment with informed proposers was also conducted. We observe high rejection rates with covered response. These are explained by responders’ resistance to unfairness. But the r...

Three studies examined the associations between relational adult attachment and moral judgment. Study 1 shows that attachmentrelated anxiety and avoidance are uniquely and differentially related to moral concerns. Relative to low insecurity, higher avoidance was associated with weaker moral concerns about harm and unfairness, whereas higher anxiety was associated with stronger moral concerns ab...

The nature of the association between anger and 5 appraisal-action tendency components--goal obstacle, other accountability, unfairness, control, and antagonism--was examined in terms of specificity, necessity, and sufficiency. In 2 studies, participants described recently experienced unpleasant situations in which 1 of the appraisal-action tendency components was present or absent and indicate...

In this paper, we develop an analytical model to discuss the unfairness problem related with dualradio/singleradiovehicle that exists in IEEE 802.11p-based vehicular networks. According to IEEE 1609.4 standard, dual-radiovehicle accesses continuously channel through control channel interval(CCHI) and service channel interval (SCHI),but single-radio vehicle only simultaneously accesses channel i...
