Ubiquitous IMS Emergency Services over Cooperative Heterogeneous Networks

There are various emergency services based on the wireless sensor network technologies being proposed recently. However, the ability of these services/networks is inherently limited by geographical restrictions and need to be deployed in advance. This paper proposes an application level approach to enhance the service coverage and availability of emergency services.

Specifically, we augment these services with All-IP network infrastructure based on IP Multimedia Subsystem (IMS). Furthermore, we integrate the IMS Emergency Services architecture with Cooperative Network technology to provide ubiquitous emergency services. We also investigate the prime problems of cooperation between heterogeneous networks and IMS. Finally, we present and discuss the experimental results of performance in our Cooperative Emergency IMS testbed.

A Testbed for MANETs: Implementation and Learned Lessons

The Mobile Ad Hoc Networks (MANETs) is a collection of wireless mobile terminals that are able to dynamically form a temporary network without any aid from fixed infrastructure or centralized administration. The nodes of MANET intercommunicate through single-hop and multi-hop paths in a peer-to-peer fashion. The nodes are mobile, so the creation of routing paths is affected by the addition and deletion of nodes. The topology of the network may change rapidly and unexpectedly. The MANETs are useful in many applications environments such as collaborative computing and communications.

In general, the research for MANETs is focused on specific problems of the networking stack, by trying to emphasize the causes of performance degradation. Most of the work has been done in simulation, as general purpose simulators can furnish a quick and inexpensive understanding of protocols and algorithms. However, experiments in the real-world are fundamentals in order to verify the simulation results and, if necessary, to revise the models implemented in the simulators.
In this talk, I will present the implementation, experiences and lessons learned of our tesbed for Ad-hoc networks and Mobile Ad hoc Networks (MANETs). We implemented many routing protocols such as OLSR, BATMAN, DSR and AODV for real experimental evaluation. We investigate the effect of mobility and topology changing in the throughput of a MANET. We study the impact of best-effort traffic for Mesh Topology and Linear Topology. We consider many experimental models and assess the performance of our testbed in terms of throughput, round trip time and packet loss. I will present many experimental results and findings which can be very important for real applications of MANETs.
