The global stability analysis for the mathematical model of an infectious disease is discussed here. endemic equilibrium shown to be globally stable by using a modification Volterra–Lyapunov matrix method. basis method combination Lyapunov functions and matrices. By reducing dimensions matrices under some conditions, we can easily show equilibrium. To prove based on matrices, use with symmetry properties (symmetric positive definite). results developed in this paper applied more complex...

Cellular-enabled unmanned aerial vehicles (UAVs) require almost continuous cellular network connectivity to fulfill their missions successfully. However, the area (e.g., rural) they fly over may have partial coverage, making path planning of such UAV a challenging task. Recently tolerable outage duration is taken into account for UAVs, and trajectory optimization under this studied. these existing studies consider only single focus on each UAV's own separately even in multi-UAV scenarios. In...

Unmanned Aerial Vehicles (UAVs) can help data collection from ground sensors or Internet of Things (IoT) devices deployed even in hard to access areas and deliver them their destinations as relays. However, the UAV trajectories should be planned carefully due limited battery lifetimes. Recently, Age Information (AoI) has also been considered a metric quantify freshness collected during this process path UAVs are aimed optimized considering AoI. existing studies have defined AoI context...

This paper proposes a novel nature-inspired meta-heuristic algorithm called the Golden Tortoise Beetle Optimizer (GTBO) to solve optimization problems. It mimics golden tortoise beetle's behavior of changing colors attract opposite sex for mating and its protective strategy that uses kind anal fork deter predators. The is modeled based on dual attractiveness survival generate new solutions To measure performance, proposed GTBO compared with five other evolutionary algorithms 24 well-known...

Watermarking refers to a way of protecting copyright. From one perspective, watermarking algorithms are categorized as key-based and non-key-based. In the watermarking, targeted blocks selected by using key embed watermark bits; in non-key-based on other hand, bits embedded predefined position host image. general, schemes expected be more robust against removal attacks. this paper we propose two attacks algorithm, which based QR decomposition. Although supposed robust, show that they...

Intersection detection between three-dimensional bodies has various applications in computer graphics, video game development, robotics as well military industries. In some respects, entities do not want to disclose sensitive information about themselves, including their location. this paper, we present a secure two-party protocol determine the existence of an intersection entities. The presented paper allows for spaces geometry. Our approach is use intersecting plane two separation or...

Unmanned aerial vehicles (UAVs) have recently been used in many applications from surveillance to communication. UAVs can also assist the process of data collection ground Internet Things (IoT) devices thanks low deployment cost and flexibility.

While there are several studies that look at problem with varying objectives, still a need finding optimal UAV path mobile IoT both delay secure mind as main concern. In...

Cellular-connected Unmanned Aerial Vehicles (UAVs) need consistent cellular network connectivity to effectively accomplish their designated missions. However, when navigating through regions with partial coverage, such as rural areas, the task of planning flight paths for these UAV missions becomes notably intricate. Algorithms designed solve this issue require significant computational resources, making them infeasible active deployment where an algorithm must run in real time using small...

International mobile subscriber identity (IMSI) sharing-based aggregated communication aims to connect multiple Internet of Things (IoT) devices the operator's core network over same line. IoT with low data rates and long sending intervals are first grouped together assigned identity. They then take turns perform their exchanges using cellular connection, yielding huge savings in resource (e.g., number active bearers) usage. Current solutions however do not consider different device traffic...

The rapid growth of technology has led to the creation computing networks. applications Internet Things are becoming more and visible with expansion development sensors use a series equipment connect Internet. Of course, any network will also provide some challenges. main challenge IoT like other is its security. In field security, there issues such as attack detection, authentication, encryption so on.
