A Novel Optimizing Algorithm for DV based Positioning Methods in ad hoc Networks

摘要

Positioning in wireless ad hoc networks plays a major role in the development of geographic aware routing and multicasting protocols that result in new more efficient ways for routing data in multihop networks that span large geographic regions. Ad hoc network positioning is specific. It is given by network properties and hardware limitations of network devices. The capabilities of individual nodes are very limited and nodes are often powered by batteries only. To conserve energy, collaboration between nodes is required and communication between nodes should be minimized. To achieve these goals nodes in wireless ad hoc networks need to determine a device's context. Since each node has limited power, it is necessary to determine the location of individual sensor nodes without relying on external infrastructure [1, 2].
