Extensive research addressing IEEE 802.11 distributed coordination function (DCF) and 802.11e enhanced distributed channel access (EDCA) performance analysis, by means of analytical models, exists in the literature. It started mainly with the famous Bianchi's model and still continues today as several aspects have not been yet covered. Indeed, the ultimate goal is to obtain the model that provides...
In this paper the modeling of Omega Networks supporting multi-class routing traffic is presented and their performance is analyzed. We compare the performance of multi-class priority mechanism against the single priority one, by gathering metrics for the two most important network performance factors, namely packet throughput and delay under uniform traffic conditions and various offered loads, using...
In this paper we propose a cross-layer handoff ordering scheme. The frame success rate (FSR) is adopted as the basis of prioritization. Different quality of service (QoS) requirements of various applications would result in different FSR requirements. In order to indicate how critical a handoff request is, both the FSR requirement from the application layer and the FSR measurement from the medium...
