Ubiquitous Trust Management and Power Optimization for UAV Assisted Mobile Communication

Abstract

Mobile ad hoc Networks (MANETs) are the trending dynamic communication technology and it used in the intelligent communication system. The special characteristics of MANETs are that it communicates in the infrastructure less environment with high mobility and speed. Due to the nature the stability of the network is reduced and it results in the increase of the energy consumption, delay and routing overhead during communication. In order to overcome this drawbacks unmanned aerial vehicle (UAV) introduced in MANETs. So that the transmission is performed it an air medium so that the devices are protected from the ground level obstacles. In recent days UAVs are used for the transmission of highly confidential data such as military and medical applications. So that it is very essential to provide security for the devices present in the UAV-assisted MANET. For that purpose in this paper Ubiquitous Trust Management and Power Optimization (UTMPO-UAVs) are proposed and it consists of various segments such as UAVs network model, UAVs traffic model and UAVs trust model. The Trust model consists of both direct trust and indirect trust calculations. This method greatly helps to achieve high packet delivery ratio and efficiency in MANETs. The simulation is carried out in NS2 and the parameters which are used for the parameter analysis are packet delivery ratio, energy efficiency, end to end delay and routing overhead. The proposed UTMPO-UAVs approach is compared with the earlier methods such as STAP-UAV and ITCD-UAV. From outcome it is understood that the proposed approach achieves high delivery ratio and energy efficiency as well as lower end to end delay and routing overhead when compared with the earlier methods.
