“…Reported accuracy through simulations was up to 6 m, depending on the node density. Another UWB-based system was proposed by Lo et al (2008). It used a time difference of arrival (TDOA)-based algorithm for 3D location estimation, and reported accuracy of 1 to 2 m in field tests.…”

Building emergencies are big threats to the safety of building occupants and first responders. When emergencies occur, unfamiliar environments are difficult and dangerous for first responders to search and rescue, sometimes leading to secondary casualties. One way to reduce such hazards is to provide first responders with timely access to accurate location information. Despite its importance, access to the location information at emergency scenes is far from being automated and efficient. This paper identifies a set of requirements for indoor localization during emergency response operations through a nationwide survey, and proposes an environmentaware sequence-based localization algorithm that is free of signal path loss models or collection of prior data, and mitigates signal multipath effects. The algorithm enables efficient on-scene ad-hoc sensor network deployment and optimizes sensing space division by strategically selecting sensor node locations. Building information is integrated, in order to enable building-specific space divisions and to support contextbased visualization of localization results. Proposed algorithm is evaluated through a building-size simulation. Room-level accuracy of up to 87.3% was reported, and up to 15.0% of deployment effort was reduced compared with using randomly selected sensor locations. The algorithm also showed good computational speed, with negligible time required for refreshing location estimation results in simulation. INTRODUCTIONBuilding emergencies, including flooding, building collapses, terrorist attacks and especially structure fires, are big threats to the safety of building occupants and first responders. For example, public fire departments across the U.S. attended 484,500 fires in buildings in 2011, which caused 2,460 deaths and 15,635 injuries (Karter 2012). When emergencies occur, unfamiliar environments are difficult and dangerous for first responders to search and rescue, sometimes leading to secondary casualties. With the increasing number of complex buildings, and less live-fire training, first responders are twice as likely to die inside structures as they were 20 years ago, and the leading cause of these line-of-duty deaths is getting lost, being trapped or disoriented (Brouwer 2007). One way to reduce such hazards is to provide firefighters with timely access to accurate location information. It is also of critical importance for an incident commander to know the locations of deployed first responders in real time, so that decision-making process is faster and more informed.

AbstractPurpose -The purpose of this paper is to study the radio resource assignment problem in the context of a heterogeneous ad hoc network, composed of 1EEE802.15.4 sensor devices, their coordinators, mobile terminals conveying vldeo streams, and sinks. This scenario also fits to the paradigm of opportunistic networks. Design/methodology/approach -In such hierarchical heterogeneous opportunistic networks, the focus is on cross-layer scheduling of the video and sensor traffics toward the sink. The scheduling strategy proposed takes into account information coming from both physical and application layers. Evaluations are performed via simulations. Findings -Results show that the proposed cross-layer strategy significantly outperforms the maximum throughput scheduling, used as a benchmark, in case of video traffic, while preseruing the same performance for 802.15.4 traffic. Practical implications -The architecture and the relevant algorithms proposed could be used in realistic emergency-deployed networks composed by the kind of nodes considered in the paper. Originality/value -The novelty introduced is related to the application of a crosslayer design strategy in a very peculiar hierarchical heterogeneous opportunistic ad hoc network. This paper is believed to be the first published combining traditional tratfic sources with sensor generated data flows.

“…As aplicação das redes ad hoc e de sensores sem fio foram idealizadas como ferramentas para auxiliar missões críticas e temporárias [34,50,58], como uma rede de comunicação alternativa em caso de falha nos sistemas públicos [19] e o monitoramento e alerta de desastres naturais [18,34]. Considerando os aspectos de comunicação a múltiplos saltos, o sucesso da aplicação destas redes, sobretudo em missões críticas, depende da conectividade da rede.…”

“…Estes dispositivos podem ser utilizados para oferecer uma rede de comunicação temporária, efetiva e de baixo custo para equipes de resposta a incidentes. Outras aplicações incluem a criação de redes de comunicação alternativas em caso de falha nos sistemas públicos e o monitoramento e alerta de desastres naturais [18,19,34]. Nas redes ad hoc sem fio, os nós podem se comunicar sem uma estrutura pré-definida e de forma auto-organizável [50].…”
