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, MCNs enhance the performance of both the existing cellular networks and ad hoc networks. Consequently, MCN-type system is(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)
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)
Cellular operators are facing difficulties in supporting a huge increment in the subscribers due to spectrum and equipment restrictions. Substantial amount of investigation has been reported in the area of increasing call carrying capacity such as Reuse Partitioning and Directed Retry. However, such action increases the size of the network and results to(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 of(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)
