High concentration of users in a cell of a wireless LAN leads to an unsustainable traffic load at the access point (AP). An unsuitable solution to the problem will cause poor connectivity for users, severe performance degradation, and possible collapse of the wireless LAN. In this paper, we present a scheduler based on queue length at the AP and a congestion control scheme based on the channel utilization...
In this paper, we propose an architecture for load balancing, which contains an adaptive packet scheduler with a bursty traffic splitting algorithm. The scheduler has one classifier which classifies the flows into aggressive and normal flow. Aggressive flows are treated as high priority flows. Based on the buffer occupancy threshold, a trigger handler checks for load un-balance of the network and...
The differentiated services (DiffServ) model relies on the per hop behavior (PHB) in each network device to treat packets differently based on packet headerspsila DSCP (DiffServ code point). For each DiffServ compliant router, the scheduling algorithm is critical in implementing PHBs, according to which packets are forwarded. In this paper, we propose the parallel maximum urgency first (PMUF) scheduling...
