Keywords: Multihop cellular networks Single-hop cellular networks Ad hoc networks Technology and economics a b s t r a c t Recently, multihop cellular networks (MCNs) were proposed to preserve the advantages of traditional single-hop cellular networks with multihop ad hoc relaying networks, while minimizing the drawbacks that they involved. In this way,(More)
A clustered multihop cellular network (cMCN) architecture is recently proposed and studied using fixed channel assignment (FCA). In this paper, we propose to use dedicated information ports (DIPs) as clusterheads for cMCN and develop a multihop dynamic channel assignment (mDCA) scheme, including two different channel searching strategies. The mDCA is based(More)
Real time locating system (RTLS) becomes increasingly popular due to its wide application and fast growth as indicated by the number of mobile devices. Instead of the conventional received signal strength indication (RSSI) fingerprinting method that performs wireless localization by collecting the received signal strength (RSS) for beacons from Wi-Fi access(More)
— The inspiration behind the wireless world came from the need to provide users with mobility and to offer an alternative to the limitations of wired mediums. As a result, there are various wireless mobile technologies like GSM, GPRS, WLAN, and Bluetooth available. The user interface and the size of mobile devices are one of the main concerns in the design(More)
This research aims to develop a new sensor-based localization technique which is exclusively used for forest fire detecting systems. Our algorithm addresses three key criteria of forest fire detecting systems deployed in nature, which are: low complexity, high efficiency and low power consumption, by the 2 features: estimating a grid-based output and(More)
Whereas cellular systems have traditionally adopted single-hop transmissions between the mobile station (MS) and the base station (BS), researchers expect multihop transmission to be utilised in the future. Cellular systems present several challenges, such as channel assignment, which are exacerbated by multimedia service traffic and an increasing number of(More)
