DCRS: A DYNAMIC CONTENTION RESOLUTION SCHEME FOR WIMAX NETWORKS
IEEE 802.16e has received wide attention as it supports high data rates and incredible pervasive connectivity with high Quality of Service (QoS) capabilities. To support QoS, many Bandwidth REQuest (BW-REQ) mechanisms are suggested in the literature for resource reservation in mobile WiMAX networks....

| description | IEEE 802.16e has received wide attention as it supports high data rates and incredible pervasive connectivity with high Quality of Service (QoS) capabilities. To support QoS, many Bandwidth REQuest (BW-REQ) mechanisms are suggested in the literature for resource reservation in mobile WiMAX networks. There are chances for performance degradation with increase in the number of requests. QoS can be ensured if a contention resolution scheme is designed for sending BW-REQs to the Base Station (BS). To improve the efficiency of the random access mechanisms in the standard, a new mechanism called Dynamic Contention Resolution Scheme (DCRS) is proposed for IEEE 802.16e networks. DCRS groups the requests based on their service types and dynamically calculates the number of Contention slots based on the Arrival Rate (?) of requests. |
