Mesh-based multicast routing protocols for mobile ad hoc networks (MANETs) build multiple paths from senders to receivers to deliver packets even in the presence of links breaking. This redundancy results in high reliability/robustness but may significantly increase packet overhead. This paper proposes a mesh-based multicast protocol, called centered protocol for unified multicasting through an...

We present a detailed 3D kinematic analysis of the central regions ($R<30''$) low-mass and dynamically evolved galactic globular cluster NGC 6362. The study is based on data obtained with ESO-VLT/MUSE used in combination adaptive optics module providing $\sim3000$ line-of-sight radial velocities, which have been complemented Hubble Space Telescope proper motions. quality number available veloci...

Packets in anonymous networks are fully protected. Therefore, traditional methods relying on packet header and higher layer information do not work to detect Distributed-Denial-of-Service (DDoS) attacks in anonymous networks. In this paper we propose to use observable statistics at routers that need no packet inspection to infer the presence of an attack. We propose packet resistance as a metri...

The computer networks have evolved themselves into an altogether new generation with Mobile Ad-Hoc networks. The Mobile Ad-Hoc Networks are increasingly becoming more sophisticated and complex in terms of topology, routing and security. The new age MANETs incorporate routing of heavier traffic classes like audio, video and multimedia. It has become important to study the performance characteris...

We present three-dimensional simulations of core-collapse supernovae using the FLASH code that follow progression explosion to stellar surface, starting from neutrino radiation hydrodynamic neutrino-driven phase performed with Chimera code. consider a 9.6 M☉ zero-metallicity progenitor both 2D and 3D models 10 solar-metallicity model, all simulated until shock breakout in while tracking 160 nuc...

The exact propagators of two one-dimensional systems with timedependent external fields are presented by following the path-integral method. It is shown that the Bloch acceleration theorem can be generalized to the impulsemomentum theorem in a quantum version. We demonstrate that an evolved Gaussian wave packet always retains its shape in an arbitrary time-dependent homogeneous driven field. Mo...

In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...

ADecision DiagramMachine (DDM) is a special-purpose processor that has special instructions to evaluate a decision diagram. Since the DDM uses only a limited number of instructions, it is faster than the general-purposeMicro Processor Unit (MPU). Also, the architecture for the DDM is much simpler than that for an MPU. This paper presents a packet classifier using a parallel EVMDD (k) machine. T...

Differentiated services (DiffServ) networks use two type of routers: edge routers mark the packet headers according to their service profile, while the core routers implement queue management to provide service differentiation between packets according to information in their packet headers. Most previous studies on the performance of DiffServ have considered either the effect of the edge marki...
