The most popular Differentiated Services composed of two key components: traffic conditioning and PHB (Per Hop Behavior). This paper addresses the affects of a packet handling mechanism LLQ (Low Latency Queuing) and several dropping schemes to quality of service in term of delay, jitter and packet loss. These schemes include RED (Random Early Detection), WRED (Weighted Random Early Detection) and...
There are many studies dealt with handoff management in mobile communication systems and some of these studies presented handoff schemes to manage this important process in cellular network. All previous schemes used relative signal strength (RSS) measurements. In this work, a new proposed handoff scheme had been presented depending not only on the RSS measurements but also used the threshold distance...
The IEEE 802.11 e defines the hybrid coordination function (HCF) which specifies the QoS algorithms in the MAC layer of the WLAN. HCF controlled channel access (HCCA) is based on centralized polling mechanism and provides parameterized QoS. This paper proposes an optimized traffic scheduling algorithm for variable bit rate (VBR) over HCCA, which can allocate network resource based on actual flows...
