In wireless network system the resources are limited. Therefore, managing resources is considered as a challenging task. The resource are distributed among attached UEs, so allocating resources needs to be well controlled. Packet scheduler in LTE network is responsible for assigning resources to attached UEs. Also, femtocell network is considered as promising solution for poor channel in indoor environment...
LTE Femtocells are designed to increase capacity and coverage especially for the indoor and cell-edge mobile users. Typically, they are deployed to offload the macrocell. However, due to co-location of femtocells in macrocell coverage, the co-tier and cross-tier interferences are high. Fractional Frequency Reuse mechanism (FFR) is one of the most effective femtocell interference avoidance techniques...
LTE networks are deployed to increase capacity and coverage especially for the indoor and cell-edge mobile users. However, such deployment comes with major challenges, radio resource management and inter-cell interferences. Fractional Frequency Reuse mechanism (FFR) is one of the most effective interference avoidance techniques. In this paper, we evaluate an existing adaptation process that adjusts...
LTE Femtocells are designed to increase capacity and coverage especially for the indoor and cell-edge mobile users. Typically, they are deployed to offload the macrocell users. However, due to co-location of femtocells in macrocell coverage, the co-tier and cross-tier interferences are high. The interference levels are different for each femtocell access mode. In this paper, we conduct experiment...
The employment of femtocells has been considered as a promising approach for increasing network capacity and enhancing end users' QoS and throughput as well as low cost and simple deployment. Deploying femtocells is common in indoor environment such as residential buildings comprising adjacent apartments. However, dense deployment of femtocells introduces interference among femtocells and the undesirable...
In many applications, the exact location of the sensor nodes is unknown after deployment. Localization is a process used to locate sensor nodes' positional coordinates, which is vital information. The localization is generally assisted by anchor nodes that are also sensor nodes but with known locations. Anchor nodes generally are expensive and need to be optimally placed for effective localization...
Real-time systems are often designed using preemptive scheduling and worst-case execution time estimates to guarantee the execution of high priority tasks. There is, however, an interest in exploring non-preemptive scheduling models for real-time systems, particularly for soft real-time multimedia applications. In this paper, we propose a new algorithm that uses multiple scheduling strategies for...
