Adaptive Power Control for Quality of Service Improvement in WCDMA Wireless Networks
نویسنده
چکیده
In third generation (3G) cellular networks, WCDMA is a widely used technique for Quality of Service (QoS) improvement because of its high data transmission rate. Power control scheme is also very essential to reduce interference and improve network performance. Existing techniques are rarely considered for the power controlling scheme along with Resource Allocation for different traffic classes. This paper proposes a Resource Allocation with Connection Admission Control (RA-CAC) scheme, along with a power control scheme for improving Signal strength as well as providing a handoff in WCDMA Wireless networks. According to the proposed scheme, the transmitted power during the session entry is controlled using a constrained Power Control (PC). The simulation results show that the proposed scheme can significantly increase throughput, residual energy & reduce call blocking probability as well as delay.

متن کاملA Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
