Location service provides position of mobile destination to source node to enable geo-routing. Previous location service protocols suffer from partial flooding overhead, and/or location failures in group movement scenarios. To overcome those deficiencies, we propose a quorum-based location service. The basic idea is that destination node registers its location along a `column' to form an update quorum. Source node makes a query along a `row' to form a search quorum. The destination location is found at the intersection between the update and search quorums. Four strategies are proposed to adjust the quorum system. To guarantee the success of location retrieval, both search and update quorums are extended by face routing which traverses outer network boundary
