This volume contains all accepted papers of the ERCIM Workshop on eMobility, which has been held in Coimbra, Portugal, on May 21, 2007. Papers from three main areas have been selected for the workshop. The workshop papers discuss several topics of the ERCIM eMobility working group, namely – Traffic engineering and mobility management – Wireless (sensor) networks – Pervasive computing and mobile applications. The goal of the ERCIM workshop is to foster collaborative work within the European research community and to increase co-operation with European industry. Current progress and future developments in the area of eMobility should be discussed and the gap between theory and application should be closed.
