Service providers will be experimenting new options for ensuring seamless services in minimum time with the motif of spearheading competitiveness. Wireless technology revolutionized technical environment by offering many […]
In this advanced generation of science and technologies, nothing seems to be impossible. The new emerging technologies have made every dream possible. This paper deals with Zig-Bee wireless technique. The Zig-Bee wireless personal area networks (WPANs) are ad-hoc low power networks that are basically applicable in short range distance in low cost. These networks are […]
Low-energy critical infrastructure monitoring (LECIM) applications are rapidly increasing. A communication protocol developed to fulfill the LECIM requirements is the novel IEEE 802.15.4k standard. In this paper, we study the impact of priority channel access (PCA), a feature defined for high priority message transmissions in the IEEE 802.15.4k standard, in LECIM DSSS physical layer (PHY). […]
Dynamic spectrum access (DSA) is a promising technology to alleviate the exhaustion of spectral resources. To realize DSA, new technologies that enable fast discovery of the unused spectrum along with efficient spectrum management must be developed. In this paper, we propose a novel scanning algorithm and access etiquette to provide secondary devices differentiated spectrum access […]
Future-generation wireless networks are increasingly ubiquitous, which allows countless numbers of netizens to create, share and access live video sequences with several content forms and textures. As a result, there emerges a dire need for mechanisms to assess the quality of video transmission. Today’s Mobile Networks are capable of solving many communication problems. However, it […]
Wireless sensor networks (WSN) are used in many fields such as industrial control, building automation, environmental monitoring, etc. IEEE 802.15.4 standard defines the features of MAC layer and physical layer for WSN. Many analytical models studied the performance of the multihop IEEE 802.15.4 networks under the assumption of ideal wireless channel, and they did not […]
The Voice over IP (VoIP) service demands high priority over other services and applications. Some constrains are associated with this real-time service, such as delay and throughput which need to be addressed before delivering to the customer. The mobility in IP networks is a demand that facilitates IP applications and services, especially in wireless networks. […]
The evaluation of Cognitive Radio (CR) for Wireless Sensor and Actuator Networks (WSANs) in industrial wireless automation applications is presented in this contribution. Current wireless solutions do not ensure enough performance for hard real-time and reliability requirements, based on time-critical data traffic. These industrial applications are characterized by harsh environments, where the robustness of wireless […]
Software Defined Network (SDN) empowers network operators with more flexibility to program their networks. In SDN, dummy switches on the data plane dynamically forward packets based on the rules which are managed by a centralized controller. To apply the rules, switches need to write the rules in its flow table. However, because the size of the flow table […]
In recent years, information-centric network (ICN) has attracted significant attention from both academia and industry. ICN is characterized by name-based routing, in-network caching and many other advanced network layer techniques. To get the benefit from these new network layer techniques, the network requires severe changes. However, considering the difficulty of deploying a new service on […]
