Qos provision is considered as the complex task due to the heterogeneous nature, diverse QoS requirements of emergent different applications. With the advent of high bandwidth 3G/4G technologies, like LTE, LTE-advanced, the necessity of QoS provision becomes even crucial. Uplink scheduling with QoS provision is considered here. The contribution of this work is uplink packet scheduling scheme maintaining...
A wireless body area sensor network (WBASN) is a wireless networking technology that interconnects tiny nodes with sensing capabilities in, on or around a human body. The vital-sign information collected by these sensors can then be used by care-givers to assess the health of a patient. Therefore, it is necessary to provide reliable communication services to prioritized WBASN data streams with quality...
Cooperative communications have been demonstrated to be effective in combating the multiple fading effects in wireless networks, and improving the network performance in terms of adaptivity, reliability, data throughput and network life time. In this paper, we investigate the use of cooperative communications for quality of service (QoS) provisioning in resource-constrained wireless sensor networks,...
Wireless mesh networks (WMNs) are emerging as a promising technology for backhauling data traffic from wireless access networks to the wired Internet. Such networks are expected to support various types of applications with different quality of service (QoS) requirements. In this paper, we provide a complete cross-layer solution for WMNs together with its OPNET simulation architecture that comprises...
Efficient communications are crucial for disaster response and recovery. However, most current public safety land mobile radio (LMR) networks only provide narrowband voice service with limited support of low-speed data services. In this paper, we study to enhance the interoperability of LMR with commercial wireless cellular networks, by which a wide variety of benefits can be offered to disaster responders,...
Multihop wireless mesh networks (WMNs) are considered a promising technology to backhaul heterogeneous data traffic from wireless access networks to the wired Internet. WMNs are expected to support various types of applications with diverse quality of service (QoS) requirements, such as end-to-end packet delay, throughput, and packet-error-rate (PER). Recent works in this area are mainly concentrated...
