نرم افزار توموگرافی شبکه در شبکه ad-hoc تلفن همراه با استفاده از الگوریتم stitching

In this paper, a network tomography (NT) approach is proposed to study network performance in ad-hoc networks. An analysis of network performance is presented in a dynamic MANET. An expectation–maximization (EM) algorithm is used in NT to estimate the network performance parameter in accordance with network performance observations. Over the dynamic network, a new algorithm has been proposed, called the stitching algorithm, to aggregate dynamic performance values for network links. Specifically, the stitching algorithm gives local and global performance parameters such as link delays over specified time periods. Therefore, the network behavior as well as the corresponding local network performance in a mobile network can be derived over a continuous period.
