Important Characteristics of the Manhattan Mobility model

* The mobile node is allowed to move along the grid of horizontal and vertical streets on the map. * At an intersection of a horizontal and a vertical street, the mobile node can turn left, right or go straight with certain probability. * Excepting the above difference, the inter-node and intra-node relationships involved in the Manhattan model are the same as in the
