The Internet of Vehicles (IoVs) is an emerging paradigm aiming to introduce a plethora of innovative applications and services that impose a certain quality of service (QoS) requirements. The IoV mainly relies on vehicular ad-hoc networks (VANETs) for autonomous inter-vehicle communication and road-traffic safety management. With the ever-increasing demand to design new and emerging applications for...
In this work, we propose a novel quality link metric; Bandwidth adjusted Inverse ETX (BIETX) for Static Wireless Multi-hop Networks (SWMhNs). The proposed metric considers two path selection parameters into account i.e., packet delivery ratio and link capacity. For computing packet delivery ratios in BIETX, the mechanism of Expected Transmission Count (ETX) is adopted. On the other hand, we take two...
Energy is one of the most precious resource in Wireless Sensor Networks (WSNs) which is mainly consumed in communication, sensing and processing. Performance evaluation of WSN routing protocols primarily rely on simulation-based studies. Most of these studies only assume oversimplified First Order Radio Model (FORM) and ignore node's energy consumed in sensing and processing. This paper presents an...
This paper presents cooperative routing scheme to improve data reliability. The proposed protocol achieves its objectives, however, at the cost of surplus energy consumption. Thus sink mobility is introduced to minimize the energy consumption cost of nodes as it directly collects data from the network nodes at minimized communication distance.
Underwater Acoustic Sensor Networks are considered to provide efficient monitoring tasks in aquatic environment but due to limited battery resource of sensor nodes, network lifetime collapses. Energy balancing is the major issue in low network lifetime. High energy consumption creates energy holes and ultimately leads to shorter network lifetime. Therefore, energy consumption must be balanced to increase...
Underwater wireless sensor networks (UWSNs) are meant to be deployed at the areas that need to be monitored continuously without the human assistance. Therefore, these networks are expected to stay operational for a longer period of time. However, sensor nodes in these networks are equipped with limited energy (e.g., battery) resources. Moreover, uneven energy consumption is one of the biggest challenges...
A significant demand has been increased in broadband services that needs very fast response time while still demanding high quality of service, which requires large bandwidth. Due to ever-increasing demands, communication in all-optical networks requires novel routing techniques. In this paper, Cartesian Optical Routing technique is presented and a comparison with conventional IP based electronic...
