Inaccuracy of Location Information as a Consequence of Data Collection Delay and Presence of Misbehaving and Malicious Nodes

This paper presents an overview of current research investigations within the WHERE-2 Project with respect to possibilities of usage of geo-location information for protocol and system optimizations. In this work we would like to underline that incorporating the knowledge of nodes’ location in protocol design and optimizations one should be aware of the associated additional ”cost” in terms of increased communication overhead and processing requirements, as well as potential inaccuracy of the location information. We ellaborate on the example where location information becomes stale due to nodes’ mobility and delays caused by transmission and propagation delays. Presence of malicious nodes can be another reason for erroneous location estimation. We demonstrate the importance of choosing localiza- tion techniques that are robust towards misbehaviours.
