Editorial on "QoS and service provisioning for integrated wireless networks"
In recent years, the increased demand for all types of wireless services, as well as the increasing number of users in the wireless networks have led to the development of different wireless technologies, such as 3G networks, WLAN, WiMAX etc, with different advantages and disadvantages in terms of coverage, bandwidth, QoS, cost and mobility. Wireless users can only benefit from the integration ...
متن کاملA Global QoS-Aware Service Composition in Wireless Sensor Networks
Wireless sensor networks (WSN) present a challenging programming environment because of their limited resources, heterogeneity and highly dynamic nature. Service oriented computing (SOC) can simplify application development by hiding platform-specific capabilities behind services. Their services are dynamically discovered and used at run time, enabling application to be platform independent and...
متن کاملQuality of Service (QoS) Provisions in Wireless Sensor Networks
In this paper, we discuss the QoS requirements in WSNs and present a survey of some of the QoS aware routing techniques in WSNs.Wireless sensor networks (WSNs) are required to provide different levels of Quality of Services (QoS) based on the type of applications. Providing QoS support in wireless sensor networks is an emerging area of research .Due to resource constraints like processing power...

متن کاملQoS for Wireless Sensor Networks: Service Differentiation at the MAC Sub-Layer
Providing service differentiation in wireless sensor networks while proposing simple and highly scalable solution is a challenging problem. We retain the use of CSMA/CA as access protocol because of its simplicity, versatility and good scalability properties. We developed CoSenS on the top of it to address its weaknesses while facilitating the implementation of scheduling policies. In this arti...
