We propose a joint multi-layer planning algorithm for IP over flexible optical networks, and use it, to compare the performance of joint as opposed to sequential multi-layer network planning in terms of spectrum and cost.
The new paradigm of molecular communication aims to utilize biological components and systems for developing communication systems. One promising candidate for molecular communication is the use of bacteria to carry information between different nanomachines. However, there is a lack of connection between molecular communication and the design of nanomachines for payload delivery. Utilizing molecular communication […]
This study presents a new methodology for modelling and handling with aggregated harmonic loads and linear loads in the harmonic power flow analysis. This method, so-called variable load method, can be used in balanced and unbalanced systems and for deterministic and stochastic studies. The main types of harmonic loads and their participation coefficients inside the […]
In this paper, we consider the case where two communicating cognitive radio users are not near to each other or have no direct line of sight(LOS). Some secondary users don’t need the entire spectrum available to them because of their traffic demand being low. If we are able to use this unused spectrum to relay […]
Products have similarities which can be analyzed to recommend products to consumers with different preferences. This paper combines Primitive Cognitive Network Process (PCNP) and Self-Organizing Map (SOM) to cluster products into appropriate categories on the basis of consumer preferences and product similarities. PCNP is an ideal alternative of Analytic Hierarchy Process (AHP) to quantify the […]
Resource allocation is an important factor in providing different varieties of services in next generation broadband wireless systems. In this paper we consider dynamic routing and subchannel allocation for providing Quality of Service (QoS) in the downlink of OFDMA networks enhanced with buffering relays. Specifically, we consider satisfying the QoS requirements of both delay-sensitive users […]
Traffic grooming has evolved to present some new features in sliceable bandwidth-variable transponder enabled elastic optical networks (SBVT-EON). One of the new features is “optical traffic grooming,” in which multiple optical flows from/to different sources/destinations can be groomed onto a sliceable transponder. When establishing a new connection request in SBVT-EON, a key problem is how […]
In Cyber-Physical Networked Systems (CPNS), the adversary can inject false measurements into the controller through compromised sensor nodes, which not only threaten the security of the system, but also consume network resources. To deal with this issue, a number of en-route filtering schemes have been designed for wireless sensor networks. However, these schemes either lack […]
Transparent optical circuit switching can improve the aggregate bandwidth, scalability, and cost of data center networks provided it can meet the performance requirements on switching speed, port count, and optical efficiency. Here, we examine the theoretical scaling limits of transparent non-blocking optical switches based on MEMS electrostatic tilt mirror devices. Using physical optics and electromechanics, […]
We investigate the repair problem for wireless caching networks when parts of stored packets in cashing nodes are lost. We first develop theoretical lower bounds on the number of necessary transmission packets over error-free broadcast channels for repair. Then we discuss the impact of the distribution of the lost packets among caching nodes. Finally, we […]
