In the context of forest fire management, wireless communication is an indispensable tool. It insures events information transmission and communication between fire defenders. Traditionally, cellular networks (CNs) are used during crisis. However due to the lack of population in far forests, CNs suffer from coverage problems. In addition, the experience has proved some reachability and capacity problems...
During a crisis situation, the incident commanders have to tackle several problems simultaneously, e.g., (1) the monitoring of a crisis evolution, (2) guiding and tracking of rescue persons and intervention robots, (3) monitoring rescue persons' health, etc. Thus, several solutions based on wireless sensor networks (WSNs) and cellular networks have been proposed. However, the real life experience...
The basic role of a wireless sensor network (WSN) is to collect information from the environment by many sensor nodes (SNs). The SN typically has a finite battery life and nodes' failures can lead to network partition. Therefore, it is important to minimize the energy usage of each sensor node and to manage the power of SN in critical position that their failure could divide the network. The current...
The main goal of wireless sensor networks is to gather information from the region of interest through a large number of micro sensor nodes. This gathering is based on a communication architecture such as client/server which consumes a lot of power and doesn't take in consideration the information properties. In this paper, we propose a new communication architecture for wireless sensor networks based...
