Higher integration lowers total cost of ownership (TCO) in the data center by reducing equipment cost and lowering energy consumption. However, higher integration also makes it difficult to achieve guaranteed quality of service (QoS) for shared resources. Unlike many other resources, memory bandwidth cannot be finely controlled by software in existing systems. As a result, many systems running critical,...
Internets of Things (IoT) are network of interconnected devices and communicate through internet. IoT constitutes huge number of heterogeneous devices and is prone to many issues. Devices in IoT senses enormous information that needs lots of network resources. In this work we have designed a Fuzzy Interference System (FIS) for classification of the jobs in to emergent and non-emergent jobs at local...
Non-orthogonal multiple access (NOMA) is considered as a promising candidate for fifth generation (5G) wireless networks. Although, NOMA promises large data rates, however, it also offers significant interference especially when the number of users is large. Therefore, in this paper, we propose a low complexity orthogonal frequency division multiple access (OFDMA)-based NOMA system, which uses the...
In this paper, we propose an auction based spectrum allocation scheme considering a primary user (PU), who is willing to sell the unused spectrum bands to multiple secondary users (SUs). Each SU is allowed to place multiple bids-each bid is a tuple consisting of amount of bandwidth requested and the corresponding price the SU is willing to pay for that bandwidth. The bids from a SU follow a typical...
The ever increasing demand for high bandwidth, low latency multimedia applications on mobile devices is set to pose a considerable challenge on the bandwidth allocation and multiplexing mechanisms in LTE and future wireless networks. One of the most important factors that diminish the quality of viewing experience of delivered videos is frequent client side rebuffering events. This paper proposes...
This paper considers a game between a power-limited authorized user and a power-limited jammer, who operate independently over the same AWGN channel consisting of multiple bands. We explore the possibility for the authorized user or the jammer to randomly utilize part (or all) of the available spectrum and/or apply nonuniform power allocation. It is found that: either for the authorized user to maximize...
The rapid growth in world-wide communications and the rapid adoption of the Internet has significantly modified our way of life. The traffic behavior is changing rapidly and the increasing mobility of traffic sources makes grooming more complex. To fulfill the needs of the future Internet, optical transmission and networking technologies are moving toward to the goals of greater efficiency, flexibility,...
Passive optical network (PON) deployment requires significant capital and operational costs for operators to provide high network capacity and significant geographic coverage. Network sharing is desirable for operators to reduce the investment needed to deploy and operate PON networks. In this paper, we introduce a bandwidth resource sharing framework for XG-PONs among multiple operators. In this...
Network Virtualization is one of the most promising technologies for future networking. Network Virtualization allows multiple virtual networks to coexist on same shared physical infrastructure simultaneously. One of the crucial keys in Network Virtualization is Virtual Network Embedding, which provides a method to allocate physical substrate resource to virtual network requests. In this paper, we...
Device-to-device transmission technology can help base stations achieve high transmission rates and meet high-capacity requirements. It is also a key technology for future markets. Additionally, the coexistence of licensed and unlicensed bands will be relevant to the landscape of the emerging 5th-generation cellular systems. However, there is a shortage of research on efficient transmission during...
The successful virtualization of wireless access networks is strongly affected by the way in which radio resources are managed. The infrastructure provider (InP) is required to deploy efficient and flexible resource allocation techniques to dynamically allocate the resources for the users associated with different mobile virtual network operators (MVNOs). Service contracts with different MVNOs and...
Multi-granularity memory system provides multiple access granularities for the applications with various spatial localities. In the multi-granularity access pattern, the one-size-bandwidth NoC design cannot utilize the bandwidth efficiently. We propose a novel NoC design, called BoDNoC, which can merge multiple narrow subnets to provide various bandwidths for access data. The new design also adopts...
This paper investigates resource allocation algorithms that use limited communication - where the supplier of a resource broadcasts a coordinating signal using one bit of information to users per iteration. Rather than relay anticipated consumption to the supplier, the users locally compute their allocation, while the supplier measures the total resource consumption. Since the users do not compare...
A new approach to implementation of the virtual network embedding strategy over OpenStack cloud platform presented. We presented the OpenStack cloud platform and the problems associated with virtual network embedding. Then, conduct OpenStack dashboard customization to generate virtual network requests to process these requests. We modified OpenStack Compute module to provide bandwidth limitation for...
The SLICE architecture for a 6-node network with its components is analyzed. Balanced load spectrum allocation and shortest path with maximum reuse are simulated to address the routing and spectrum allocation. The algorithms results show the reduction in sub-carrier utilization in a SLICE optical network. The simulation results also gives us the maximum subcarriers utilized in each case for various...

P2P is an essential technology to solve the gap between server's capability and growing demand of client. In P2P system, there is a natural imbalance. Thus, Load balance is one of the main research directions. Better balance performance would lead to higher bandwidth, higher resource utilization, and better network stability. Churn is a normal phenomenon in P2P network, which often brings some awful...
Spectral efficiency and energy efficiency are important design criteria for green communications.
