Wireless sensor networks (WSN) nowadays are used in variety of applications having various quality of service (QoS) requirements. Hence they are required to provide different levels of Quality of Services based on the type of applications. As these Wireless Sensor Networks are constrained by the processing speed, memory capacity, energy more concentration is given in these area ignoring other parameters...
The Internet of Things (IoT) is the result of many different enabling technologies such as embedded systems, wireless sensor networks, cloud computing, big-data, etc., which are used to gather, process, infer, and transmit data. Combining all these technologies requires a research effort to address all the challenges of these technologies, especially for sensing and delivering information from the...
Due to complex surveillance in environment, more and more wireless multimedia sensor networks (WMSNs) is becoming an important hot problem in network research area. Especially, the QoS-controlled architecture is a key and significant problem. Based on the distributed policy and three-dimensional hierarchy protocol model, a novel QoS architecture for distributed control is introduced and analyzed in...
Combining cross-layering and autonomic paradigms is considered, until now, the best alternative for better Quality of Service (QoS) support in wireless networks. We adopt this combination in the design of a new architecture called Cross- Layer Engine (XLEngine) having the ability to make optimizations based on local and network wide knowledge. The unique mode to acquire this network knowledge is that...
Wireless Multimedia Sensor Networks (WMSNs) is comprised of small embedded video motes capable of extracting the surrounding environmental information, locally processing it and then wirelessly transmitting it to parent node or sink. It is comprised of video sensor, digital signal processing unit and digital radio interface. In this paper we have surveyed existing WMSN hardware and communication protocol...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
