This survey paper is intended to provide an overview of the main ad hoc paradigms that can be applied to disaster response networks, highlighting their applicability to important tasks in disaster relief operations. In this way, we also review the main works found in the literature which employed ad hoc networks in disaster scenarios. Finally, we provide open challenges and future research directions...
Broadcast schemes play an important role in the performance of mobile ad hoc networks. They are widely used as a dissemination mechanism and as a part of the discovery phase of routing protocols. The simple flooding algorithm is the usual mechanism employed in mobile ad hoc networks, but it has been demonstrated its inefficiency in congested scenarios due to the high number of collisions and contentions...
A hybrid broadcast scheme for mobile wireless networks is proposed in this letter. The main objective is to combine different flooding schemes in order to solve the broadcast storm issue encountered by the simple flooding scheme. For this purpose, the density of nodes is taken into account using a density metric called expansion metric. In addition, in order to reduce the broken links due to mobility...
A basic framework for wireless based mobile distributed environments is given by the wireless CORBA specification. It provides a generic solution hiding the underlying network level details from applications. However, in Blue tooth networks, it exhibits some problems when dealing with multi-user environments, like power consumption limitations of mobile devices or Blue tooth role assignment. This...
The idea of this paper consists of developing a new methodology based on a complex system that will be analyzed and programmed by several groups of students that must work openly and cooperatively to achieve a final global result. For this purpose, a personal digital assistant developed as an open hardware called OpenMoko has been selected. The paper details the experience of working with this system...
