Concentrating on the influence of DDoS applied to ad hoc networks, we introduced three classic queue management algorithms: Drop-Tail, random early detection (RED), and exponential marking (REM). We analyzed compared defensive abilities these algorithms networks with NS2 under attack. The results showed that active algorithms, such as REM RED, exhibited stronger than passive algorithm Drop-Tail medium- small-scale attacks; however, large-scale attack, all insufficient capabilities. This...

Coverage is one of the important performance indexes in wireless sensor networks. When target covered by k degrees sensor, more redundant data are generated, which may lead to network congestion, thus reducing communication and coverage leading a rapid depletion energy. Therefore, this paper presents an energy balance control algorithm for overlay model based on node position relations. Areas given analysis model. In terms consumption, nodes with low consumption scheduled proportion expected...

The rapid motorization of cities has led to the increasingly serious contradiction between supply and demand road resources, intersections have become main bottleneck traffic congestion. In general, capacity delay are often used as indicators improve intersection efficiency, but auxiliary such vehicle emissions that contribute sustainable development also need be considered. It is necessary evaluate efficiency through multiple measures reflect different aspects traffic, these may conflict...

Introduction Endometrial Carcinoma (UCEC) is a prevalent malignant tumor within the female reproductive system. HLA-DMB, beta chain of non-classical MHC class II protein HLA-DM, has been implicated in progression various cancers. However, its role development endometrial carcinoma remains unclear. Therefore, we conducted preliminary exploration prognostic value and potential mechanisms HLA-DMB uterine corpus (UCEC). Methods The differential expression was analyzed 554 samples 35 normal...

Multi-scale maps are essential representations of surveying and cartographic results, serving as fundamental components geographic services. Current image generation networks can quickly produce map tiles from remote-sensing images. However, generative models designed for natural images often focus on texture features, neglecting the unique characteristics features scale attributes tile maps. This limitation in impairs accurate representation information, quality still needs improvement....

In traffic flow prediction, many external factors, such as weather and holiday have a significant impact on flow. However, previous research prediction mainly focused the internal correlations within data, failing to integrate or comprehensively factors affecting build models. Based this, this study collected possible data of integrated these construct model. This proposes Temporal Graph Convolutional Network algorithm (IM - GCN), which integrates multi source heterogeneous that affect for...

This study introduces a novel nonlinear dynamic analysis method, known as beluga whale optimization–slope entropy (BWO-SlEn), to address the challenge of recognizing sea state signals (SSSs) in complex marine environments. A method underwater acoustic signal recognition based on BWO-SlEn and one-dimensional convolutional neural network (1D-CNN) is proposed. Firstly, particle swarm (PSO-SlEn), BWO-SlEn, Harris hawk (HHO-SlEn) were used for feature extraction noise SSS. After 1D-CNN...

With the emergence of various applications in intelligent transportation systems (ITS), cooperative communication among nodes on roads is becoming more and important vehicular networks. However, selfish nodes, which are not willing to relay data packets for others, drastically decrease performance network aspects including packet delivery ratio, end-to-end delay, bandwidth, etc. It critical detect avoiding decrement performance. Nevertheless, it extremely challenging correctly fairly...

To avoid random and blindfold forwarding decision in spray wait routing delay tolerant network, Binary Spray Wait based on average delivery probability is proposed this paper. Based predictability of PROPHET, used to make decision. Furthermore, we evaluate it through simulations versus protocol. The experimental results show there has slight higher rates shorter delays probability.

Cooperative communication and resource limitation are two main characteristics of mobile ad hoc networks (MANETs). On one hand, among the nodes in MANETs highly depends on cooperation because limited transmission range nodes, multi-hop communications needed most cases. other every node has stringent constraints computations, communications, memory, energy. These lead to existence selfish MANETs, which affects network performance various aspects. In this paper, we quantitatively investigate...

Efficient data delivery in vehicular sensor networks is still a challenging research issue. Position-based routing protocols have been proven to be more suitable for dynamic or large-scale mobile than traditional ad hoc protocols. However, position-based assumes that intermediate nodes can always found set up an end-to-end connection between the source and destination; otherwise, it suffers from network partitions which are very common leads poor performances. This paper addresses challenge...
