Research ArticleOpen accessPhrase in the titleAn Adaptive Modulation Scaling Scheme for Quality of Services Ensurance in Wireless Sensor NetwoksYong Yuan, Zongkai Yang, Jianhua HeEnergy consumption has been a key concern of data gathering in wireless sensor networks. Previous research works show that modulation scaling is an efficient technique to reduce energy consumption. However, such technique will also impact on both packet delivery latency and packet loss, therefore, may result in adverse effects on the qualities of applications. In this study, the problem of … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Efficient Combined Call Admission Control and Scheduling Algorithm to Improve Quality of Service for Multimedia Services Over Next Generation Wireless NetworksG. Nantha Kumar, A. ArokiasamyWe nominate a weighted service queuing approach, each service queue is allotted a preset priority weight and Call Admission Control scheme for service classes defined in IEEE 802.16 standard. Different group of queues have been implemented to transmit different service classes. Allocation of bandwidth usage of each service classes are relying on maximum data that could take part in connection … …Journal of Computer Science, Vol. 11, Issue 2 · 20 Sep 2014 · 6,482 accessesView PDFCite
