A fault-tolerant routing system is highly needed in autonomous unmanned vehicle (AUxV)-based networks because of the various constraints due to adversarial situations present in the environment of AUxVs. Critical consequences might be resulting even with a minor fault in the system software/hardware in these types of systems due to the involved hazard of their applications such as search and rescue,...
As the virtual backbone of the network, connected dominating set (CDS) plays an important role in supporting data communication, reducing the routing overhead, and enhancing the scalability of the network. Traditional CDS construction algorithms are usually applied to the networks with homogeneous nodes, e.g., a pure wireless sensor network. In the past few years, Wireless Sensor and Actor Networks...
There are more and more systems using mobile devices to perform sensing task, but it increases the risk of leakage of personal privacy and data. Data hiding is one of the important ways for information security. Even many data hiding algorithms have worked on providing more hiding capacity or higher PSNR, there are few algorithms that can achieve effective control on PSNR while ensuring hiding capacity...
Workload and resource management are two essential functions provided at the service level of the distributed systems infrastructure. To improve the global throughput of these software environments, workloads have to be evenly scheduled among the available resources. To realize this goal, several load balancing strategies and algorithms have been proposed. Most o f t h e s e strategies were developed...
Communication in Vehicular Ad Hoc Networks (VANETs) is frequently disrupted by highly dynamic, noisy and interference-prone links. This paper proposes a novel algorithm, named Cross-Layer Tree Formation (CLTF), for medium access. CLTF enables the formation of the tree architecture that connects the receiver node with the cooperative relay node in Medium Access Control (MAC)-level retransmission. The...
Internet of Things (IOT) is a wireless ad-hoc network of everyday objects collaborating and cooperating with one other in order to accomplish some shared objectives. The envisioned high degrees of association of humans with IOT nodes require equally high degrees of reliability of the network. In order to render this reliability to IOT networks, it is necessary to make them tolerant to faults. In this...
Abstract: This paper looks into the problems faced by Underwater Sensor Networks (UWSNs), with regard to energy optimization and efficient data delivery. A new algorithm is proposed which uses the properties of a "Parabola" in order to transmit data packets from source to destination. The scheme is called the "Parabola-based Routing"(PBR) algorithm. The algorithm is adaptive, and...
Distributed computing provides solution to fundamental requirement of high computational capacity for numerous complex problems in the fields of quantum physics, weather forecasting, and molecular biology. This computational ability is the result of combining computation capacity of multiple nodes together in a distributed computing system. The initialization and maintenance of the whole structure...
