Wireless body area networks (WBANs) have been developed as human body monitoring systems to predict, diagnose and treat diseases. The two important concerns for WBAN are sensor lifetime and latency. Because the signal transmission in WBAN takes place in or around the human body, the fading and collision of the channel due to other existing wireless devices affect the packet error rate significantly...
This work explores the benefits in terms of energy efficiency that can be provided by device-to- device (D2D) communications in cellular systems. Analyzing a large cellular network using stochastic geometry, considering Nakagami fading and realistic system parameters, we explore the reduction that can be achieved in network power consumption, and the impact this reduction has on the performance of...
Device-to-device (D2D) communications is a promising candidate for increasing the throughput of cellular systems towards 5G. Its current consideration for inclusion in LTE-A is attracting a lot of research interest, including work on mode selection, bandwidth allocation, and power control. Some consider the uplink for D2D operation while others focus on operation over the downlink. It is still unclear,...
Fire rescue operation is one of the most critical public safety activities where the firefighters put their lives to direct risk in order to extinguish the fire and help save other humans. For the success of fire rescue operation it is very important that the incident commander and the firefighters in the fire field are completely aware of their surroundings. Situation awareness can be achieved by...
In a fire rescue operation, a fast, reliable, and robust communication system is needed to quickly take control of the emergent situation. One of the most important issues in firefighter communication networks (FCNs) is the design of a specialized routing protocol that caters to the specific needs of the fire rescue application. This paper proposes a reliable, energy-balancing, multi-group (REM) routing...
Recently, Mobile Ad-hoc Networks (MANETs) have attracted huge attention in the field of public safety networks to realize a number of functionalities such as early warning, aiding the rescue and relief operations. First responder,s ability to communicate information among themselves and the supervisor greatly influences the success of the rescue operation. Therefore, a fast, reliable and robust communication...
Natural d isasters such as earthquakes, storms and fire scenes can led to the failure of many nodes simultaneously in wireless sensor network, leaving behind multiple isolated network segments. Establishing connectivity among different segments is possible by deploying relay nodes. There are couples of challenges in the deployments mechanism, i.e., how many relay nodes will be sufficient and where...
Recently maritime cognitive radio network is proposed to provide high bandwidth and low communication cost for maritime users. Spectrum sensing is one of the key issues to develop cognitive radio networks. Radio propagation is one of the main differences between maritime and land environment. Traditional detectors such as matched filter, energy detector and cyclostationary detector are not robust...
