Emergency response services are often delayed due to the destruction or non-availability of the communication network. This research work proposes Mobile Adhoc NETwork (MANET) architecture integrated with mobile sensing concepts, for reviving the communication network in disaster hit areas. Mobile sensing in emergency scenarios can very well address issues like victim localization etc. and offer help in providing specific information about the affected area to the responders and control stations. This paper proposes a design that utilizes the existing the mobile devices such as smartphones, laptops, etc. in the field to provide the required communication facility. A new buffer system powered flooding methodology is also proposed to cater to the challenging environment. The mobile adhoc network architecture proposed is implemented and tested using several android based mobile phones. An android application named Android app for Emergency Communication (AEC) was developed and it enabled users to send messages to emergency services as well as their dear ones even when they are in regions with no cellular coverage.
