    ELS: Energy-Aware Some-for-Some Location Service for Ad Hoc Mobile Networks
    (Springer Berlin Heidelberg, 2006) Derhab, Abdelouahid; Badache, Nadjib; Tari, Karim; Sami, Sihem
    In this paper, we propose a new location service for Ad hoc mobile networks. The network area is divided into non-overlapping zones. Using a hash function, a node identifier is mapped to a set of zones, in which the location information of the node are stored. We also propose a location information distribution scheme that achieves low rate of outdated location information. Using cross-layer design, the service can tolerate servers mobility and failure, and last for a long time period. Simulation Results show that the proposed location service experiences low overhead and high location information availability and accuracy.
