Heterogeneous networks principally composed of macro-cells overlaid with small cells (e.g., Femtocells, pico-cells, and relays) can potentially improve the coverage and capacity of existing cellular networks and satisfy the growing demands of data throughput. In Het Nets, small cells play a key role in offloading user data traffic from congested macro-cells(More)
Congestion avoidance is a vital part in improving the Quality of service (QoS) in Wireless Mesh Network (WMN). A preventive congestion avoidance algorithm is proposed in this paper which predicts the congestion before it really happens in the network by using different statistical analysis models which analyze historical traffic data in the network with(More)
Multi-hop relay technology is one of the most promising candidate technologies to overcome the coverage and capacity problem in LTE-Advanced networks. Currently 3GPP is considering the incorporation of multi-hop relays into Release 12 of LTE-A standards. However, many issues remain to be resolved due to the complexity of multi-hop relaying paradigm,(More)
Admission control is an important component to control the acceptance of new calls without degrading the Quality of Service (QoS) of the existing calls in the wireless mesh network. Two types of calls are existing in the network which are the new and handoff calls, in order to increase the admission rate for both types of calls a multi-homing admission and(More)
Serving hundreds of User Equipments onboard of a high-speed train is a very big challenge in terms of resources and mobility management. In addition to the high penetration loss, direct connection between the Evolved Node B and fast User Equipment leads to increased handoff failure rate, and increased power consumption of Vehicular User Equipments.(More)
Broadly accepted WLAN technology and the UMTS system are two most important wireless networks in the future. A lot of interests have been put in integrating these networks in order to get the benefit of both high data rate of WLAN and wide coverage area of cellular networks, and supporting end to end Quality of Service (QoS) is an unavoidable topic towards(More)
