<span lang="EN-US">The innovative idea presented in this research is that advancements automotive networks and embedded devices can be used to assess the impact of congestion control on throughput packet delivery ratio (PDR), or so-called multimedia content delivery. Vehicle networking distribution have become essential factors getting packets their intended recipients due availability ba...

While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many commercial and civilian government organiza...

2 Abstract Role-based access control (RBAC) is a promising alternative to traditional discretionary and mandatory access controls. In RBAC permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles' permissions. In this paper we formally show that lattice-based mandatory access controls can be enforced by appropriate connguration of RBAC c...

Access Control is the process or mechanism for giving the authority to access the specific resources, applications and system. Access control defines a set of conditions or criteria to access the system and its resources. There are three main accesses Control model first is Mandatory access control model, second is Discretionary access control model and third is Role based access control models...

The use of smart antennas in extending coverage range and capacity of wireless networks dictates the employment of novel media access control protocols, with which the base station (BS) or access point (AP) provides access to users by learning their locations. We consider the class of protocols that employ beamforming and use contention-based or contentionfree polling methods to locate users re...

In this paper, we propose a new security enforcement mechanism and demonstrate how this mechanism can enforce policies for both mandatory access control (MAC) and discretionary access control (DAC) in an object database system. Each class may have a security method that can block messages that leave instances of the class, and can block messages directed to instances of the class. Each supercla...
