Public Safety Networks (PSNs) provide assistance before- and post-disaster events. With the help of technological advances, PSNs are able to cope with both natural and man-made disasters, protecting people, environment and property. Effective communications, better situational awareness, lower response times and greater emergency efficiency are essential to an effective response to emergencies and disasters. Long Term Evolution (LTE) has been chosen to be the key technology for public safety networks. In this study, a performance model is presented for the PSN frameworks which use cooperative devices with LTE device to device (D2D) communications features. Mobile stations that are out of cellular network coverage range use D2D communications, where mobile stations which are in a healthy area can act as relay nodes to provide information about the location of potential victims to a central system. Since relay nodes have the potential to become bottlenecks for relatively high scale disasters, the interaction between the relay node and the base station is critically considered in this study. The analytical model and solution are suitable for assessing the quality of service for PSNs with similar infrastructures. Results obtained from the analytical model are presented comparatively with those from discrete event simulations for validation. The maximum discrepancy between the results obtained from the analytical model and the simulation results is less than 1.4%, which is within the confidence interval of the simulation.


Energy-aware routing algorithms for wireless ad hoc networks with heterogeneous power supplies
Vazifehdan, Javad; Prasad, R. Venkatesha; Onur, Ertan; Niemegeers, Ignas (Elsevier BV, 2011-10-27)
Although many energy-aware routing schemes have been proposed for wireless ad hoc networks, they are not optimized for networks with heterogeneous power supplies, where nodes may run on battery or be connected to the mains (grid network). In this paper, we propose several energy-aware routing algorithms for such ad hoc networks. The proposed algorithms feature directing the traffic load dynamically towards mains-powered devices keeping the hop count of selected routes minimal. We unify these algorithms into...
How many sensors for an acceptable breach detection probability?
Onur, Ertan; Delic, H (Elsevier BV, 2006-01-10)
Determining the required number of sensors to be deployed is a critical decision for surveillance wireless sensor networks. In this paper, we discuss the trade-off between the number of sensors and the breach detection probability considering the effects of sensor parameters. We present the weakest breach path problem formulation and provide a solution by utilizing the Dijkstra's shortest path algorithm. We propose a method to determine the required number of sensors to be deployed and to gain insight about...
Mobile multi-access IP: a proposal for mobile multi-access management in future wireless IP networks
Altuntas, S; Baykal, Buyurman (Elsevier BV, 2005-03-15)
As the wireless networking technologies advance rapidly, providing mobile users with roaming freely in heterogeneous wireless access domains, the need for multi-access arises. This paper introduces the Mobile Multi-Access Management Architecture (MMA-IP) for IP-based future wireless networks. MMA-IP enables mobile users to utilize multiple access domains synchronously and to switch between different access domains. In order to handle multi-access operations, MMA-IP defines a new special mobility agent, call...
UAVs assessment in software-defined IoT networks: An overview
Al-Turjman, Fadi; Abujubbeh, Mohammad; Malekloo, Arman; Mostarda, Leonardo (Elsevier BV, 2020-01-15)
The technological advancements in the ubiquitous IoT era and the ever-growing desire of communities to enforce smart cities with security and safety of user data as their priority, mini Unmanned Aerial Vehicles (UAVs), or drones, are perceived as a tool for raising living standards by meeting the requirements of societies. Traditionally in UAV communication links, meshed ad hoc networks were among the first options of connectivity. However, the increased demand for deploying multi-UAV networks necessitates ...
IPBM: an energy efficient reliable interference-aware periodic broadcast messaging protocol for MANETs
ÜNLÜ, BERK; Ozceylan, Baver; Baykal, Buyurman (Springer Science and Business Media LLC, 2019-07-01)
Mobile ad-hoc networks (MANETs) have been widely employed in many fields including critical information delivery in open terrains as in tactical area, vehicular or disaster area network scenarios. To provide effective network maintenance for those MANETs, it is essential to adopt proper control communication methods, which provide reliable delivery of network information. However, it is difficult to provide control communication that meets the quality of service requirements due to the broadcasting of contr...
