Context routing in heterogeneous pervasive computing fieldwork environments

This article presents a routing protocol that uses physical location information in diverse ways. This information can generate local working sub-areas, limiting the target of messages that pass through the network. Also it allows the exchange of data between different sub-areas, through the use of nodes that control the borders of the work areas. The knowledge of neighboring areas allows routing based on physical location and the exchange of information only to nodes that are physically adjacent
