Recently multi-agent patrolling became more and more crucial in security, monitoring, etc. applications. It can be used, for example, to monitor points of interest in space, such as measurement points or entrances to a guarded area. A good patrolling strategy would ensure frequent visits to all points of interest defined by a user. A variety of centralized and distributed approaches exist already...
The traffic profile of future mobile networks is foreseen as becoming more variable both in time and among base stations (BSs) due to the widespread heterogeneity in applications and services. Dynamic time division duplex (TDD) has been recognized as an important enabler to cope with this traffic variability, especially in dense networks with many BSs and a small number of user equipments (UEs) served...
A major problem in Wireless Mesh Network is capacity decrease due to wireless interference. A wireless mesh router with multiple routers and channels is capable of reducing network interference. Static channel allocation and dynamic channel allocation are types of channel allocation. Adaptive Dynamic Channel Allocation protocol (ADCA) is dynamic channel allocation protocol which decreases the packet...
The dynamic TDD DL/UL configuration based on instantaneous asymmetric DL/UL traffics is an effective way to increase the radio resource utilization. However, free reconfiguration of each cell's TDD DL/UL configuration may result in significant co-channel co-subframe DL-UL interference. In this paper, we propose and evaluate a novel centralized cell clustering interference mitigation scheme for dynamic...
For a time-sensitive application, the usefulness or the quality of the application's end result depends on the time when the result is delivered, or when the application is completed. A Time Utility Function (TUF) is often used to represent the dependency between an application's accrued value and its completion time. For parallel and time-sensitive applications, each application has multiple tasks...
The demand for wireless communication in enterprise network has been increasing with the advent of "smart working environment." In enterprise wireless network, high density of access points (APs) and limited frequency resources raise the significance of radio resource management. In this paper, we propose a centralized algorithm, named JACPoT, for jointly executable transmission power control...
Private Mobile Radio (PMR) networks are cellular infrastructures dedicated to be used by professionals, such as public safety, military, industry and transportation organizations. In those networks, resources are scarce, and there are strong Quality of Service (QoS) requirements. The emergence of new services which need more bandwidth has made the world PMR leader focus on the LTE-Advanced protocol...
Opportunistic spectrum access, which allows secondary users opportunistically access unused licensed channels to exploit instantaneous spectrum availability, is a promising approach to achieve efficient spectrum utilization and mitigate spectrum scarcity. To address the challenge of dynamic spectrum access, one of the most important issues is cooperative spectrum reallocation among secondary users...
On chip multiprocessors (CMPs) platforms, multiple co-scheduled applications can severely degrade performance and quality of service (QoS) when they contend for last-level cache (LLC) resources. Whether an application will impose destructive interference on co-scheduled applications is largely dependent on its own inherent cache access behavior characteristics. In this work, we first present case...
Designed to adapt spectrum usage on-the-fly, frequency-agile radios can drastically improve performance of wireless networks. Such flexibility, however, comes with a cost of increased hardware complexity. This motivates us to understand when and why having higher degree of frequency-agility helps and how much improvement it can lead to. In this paper, we approach this question by comparing two types...
