| Abstract |
Wireless Mesh Networks (WMNs) are formed by self-organized wireless nodes that use multi-hop wireless relaying. These networks are useable in a variety of situations ranging from fixed residential broadband networking based on rooftop wireless mesh nodes to emergency response networks for handling large scale disasters. Quick deployability, minimal configuration, broadband communication, and easiness of reconfigurability are the major characteristics that make WMNs a suitable choice for emergency applications. There exist several open research issues in using such WMNs for emergency response applications. We, in this paper, present a hybrid distributed wireless networking architecture, Extreme Networking System (ENS), and present large set of performance observations collected from a real distributed hybrid wireless mesh network used for supporting a medical emergency response application. We present the traffic behavior observed in our network when a client server medical emergency response application is employed. The performance observations on real-traffic scenarios for emergency response application underlines the need for focusing further research on topology control, reliability, service availability, and distributed management. We observed that though there are several challenges that need to be solved, a WMN is a favorable choice for emergency response networking. |

| Abstract |
Communication is crucial for first responders. Crisis management is nearly impossible without good means of communication. Unfortunately the communication technology used by first responders today does not scale well. Also most of the given infrastructure, such as cell towers, might be destroyed. In recent research ad-hoc and peer-to-peer based communication has been proposed to solve the problem of resilient communication. Most mobile devices are equipped with wireless transceivers that make them suitable to participate in ad-hoc networks. But node density might be too small for a connected topology. In this paper we, therefore, discuss the implications of an emergency switch for private wireless routers allowing them to transition to an emergency mode to create a supportive wireless mesh network. To analyze if such a network would result in a resilient topology real data from wireless routers in a city is gathered. We calculate the locations of private and public routers from GPS traces and compare the resulting networks with each other. © 2012 ISCRAM. |

| Abstract |
Communication and interoperability between different organizations of first responders has been a problem for a long time. There have been examples of failure in communication between different organizations at World Trade Center on 9/11, for example some of the police warnings were not heard by fire fighters that resulted in several lives lost. In most cases, network unavailability or incapability of coordination among networks causes much damage. Therefore, we present a highly reliable communication infrastructure that is suitable at ground zero where the existing communication network is damaged or unavailable. We used Hybrid Wireless Mesh Network (HWMN) as a candidate for communication infrastructure with the capability of working in a heterogeneous environment with different available backhaul technologies. In addition to the use of WMNs, we also present some special requirements for a cellular networks generated by simulation models investigating different scenarios that occur at ground zero. For example, when hurricane Katrina hit New Orleans, people outside the ground zero area could place a call, but were not able to receive phone calls. This happened because the cellular network elsewhere was not able to contact the Home Location Register (HLR), located at New Orleans. We, in this paper, propose a solution in which the important user or network information databases such as HLR and VLR (Visitor Location Register) are replicated to provide a sufficient amount of fault tolerance. |

| Abstract |
Networking in the event of disasters requires new hybrid wireless architectures such as Wireless Mesh Networks (WMNs). Provisioning Quality of Service (QoS) in such networks which are quickly deployed during emergencies demand radical solutions. In this paper, we provide a new QoS approach for voice calls over a wireless mesh networks during emergency situations. According to our scheme, the contention and back-off parameters are modified based on the emotion content in the voice streams. This paper also looks at methods for detecting emotion from an incoming voice call using the speech signal. The issues of interest in such situations are whether the caller is in a state of extreme panic, moderate panic, or in a normal state of behavior. The communication network behavior should be modified to provide differentiated QoS for calls based on the degree of emotion. We use several features extracted from the speech signal like the range of pitch variation, energy in the critical bark band, range of the first three formant variations, and speaking rate among others to discriminate between the three emotional states. At the back end the Gaussian mixture modeling techniques is used to model the three emotional states of the speaker. Since a large number of features increase the computational complexity and time, a feature selection technique is employed based on the Bhattacharya distance, to select the set of features that give maximum discrimination between the classes. These set of features are employed to simulate an emotion recognition system. The results indicate a promising emotion detection rate for the three emotions. We also present the early results on detecting the emotion content in the speech and using this in the MAC layer differentiated QoS provisioning scheme. Our scheme provides an end-to-end delay performance improvement for panicked calls as high as 60% compared to normal calls. |
