With the ever increasing data and computational demands from mobile users, heterogenous wireless networks (HetNets) and mobile cloud computing (MCC) have been advocated as a promising solution to meet these demands. Insufficient bandwidth is one of the most important challenges being faced by a successful implementation of the MCC technology due to heavy data traffic. The MCC implementation on HetNet...
Cognitive radio is an optimistic technology to implement the concept of dynamic spectrum access and provide a flexible way to share the spectrum among the primary and secondary users. In this paper, a game theoretic-based model is presented using the concept of Nash Equilibrium for spectrum sharing. In this model, interference and number of radios on each link are considered as parameters for designing...
Recently, mobile cloud computing (MCC) has arisen as a promising technology to augment the user equipment (UE)' capabilities in emerging 5G systems by wirelessly transferring the computation-burden from it to the resource-rich cloud computing centers. In this setting, the massive data transfer over a standalone wireless network becomes a challenging task due to the expected increased latency over...
Cognitive radio networks play a vital role in solving the problem of underutilization of spectrum by identifying unused licensed radio spectrum. They solve the problem by distributing this unused spectrum among unlicensed users in an intelligent fashion without interfering with existing users. In this paper, using the conflict graph and graph colouring concepts, a Graph Colouring based Dynamic Channel...
Cognitive radio can be considered as an enabling technology to utilize the white spaces through efficient spectrum sharing techniques. Through the Shanon capacity formula, it is clear that channel capacity is crucial for communication when licensed and unlicensed users share the channels. Further, to address the channel capacity, signal to interference plus noise ratio (SINR) plays an important role...
Due to recent advances in wireless technologies, wireless mesh networks (WMNs) are expected in the near future to fully handle content-rich multimedia services with various quality of services (QoS) guarantee. Unlike traditional data applications, multimedia applications require QoS support in order to satisfy the user's service requirements. Admission control has been advocated as a promising approach...
Wireless mesh networks (WMNs) have become immensely popular these days. In order to satisfy user service requirements, multimedia applications need quality of service (QoS) support. Since the mesh routers are usually stationary in WMNs, a better performance is expected in WMNs as compared to ad hoc networks. But sustaining QoS in wireless mesh networks still remains a challenging task. A fundamental...
