Heterogeneous Network Performance Improvement Using Proposed OLRED and OLWRED Strategies

Abstract

Abstract-The congestion and queue delay are the critical problems that may face the heterogeneous networks, because of the huge data broadcasting in every network segment. So the selection of suitable strategy to solve these two major problems is considered in this work. Therefore, this paper proposes two new strategies based on optimized link state routing protocol (OLSR), random early detection (RED) and weight random early detection (WRED), which we defined them as OLRED and OLWRED respectively. These two proposed strategies are applied and examined the performance of the heterogeneous networks in terms of three important metrics: throughput, utilization and queue delay. Our simulation results are done using OPNET and they show that the proposed strategies are improved the QoS for the heterogeneous networks and reducing the congestion with high network productivity.

A new smart approach of an efficient energy consumption management by using a machine-learning technique

“…For that, we need to define the scale, which used to measure the efficiency of the energy consumption that standard, called the power factor (𝑃 𝑓 ) [18] for the active power (𝐴 𝑝 ). We need to know the actual power transmitted to nonlinear loads [19]- [21], such as electric appliances, lighters, heaters, and laptops (kW); therefore, to calculate it we must first learn that the current (I) lagging by 90 degrees behind the voltage (V) by an angle for the electrical loads that be used in our houses, the vector diagram which is being used to describe currents and voltages that are perfectly sinusoidal signals. The current vector can be divided into two components in this vector diagram: one in phase with the voltage vector (component 𝐼 𝑎 ) and the second is lagging 90 degrees (component 𝐼 𝑟 ) [2] usually the power factor (𝑃 𝑓 ) is given in (3):…”

Proposed emerged and enhanced routing protocols for wireless networks

“…Some related works such as [10]- [14] with aggressive adding more enhancements to standard wireless routing protocols as well network performance improvement, the previous standards of conventional routing protocols (destination sequenced distance vector (DSDV), dynamic source routing (DSR), optimized link state routing (OLSR), and zone routing protocol (ZRP)) did not take care more attention about energy-efficiency issue and the capacity of those conventional routing protocols are limited principally due to scarcity of bandwidth. Therefore, by developing those conventional routing protocols, the traditional wireless systems can reduce the network overhead that will reduce significantly the node and network latency for specified bandwidth [15], [16]. Finally, this work is organized as follows: section 2 submits our proposed routing protocols with its work procedures in details, while section 3 demonstrates our experimental tests that will be done for testing our proposed routing protocols by given network example for each proposed routing protocol as a case study.…”
