Ad hoc networks used in emergency networks : the Trust Metric Routing approach

Abstract

Mobile wireless ad hoc networks have characteristics, which intuitively make them well suited for utilization in search and rescue operations. This report discusses and describes how mobile wireless ad hoc networks will strengthen the emergency network and reduce the impact of the shortcomings identified in the planned network. It is shown that mobile wireless ad hoc networks will represent extra connectivity, capacity and functionality. In order to make mobile wireless ad hoc networks even more applicable for search and rescue operations, the concept of Trust Metric Routing is proposed and described. The concept will improve connectivity considerably and lead to a significant throughput improvement within a large node density range. Aspects such as scalability and security are discussed.
