1. A system for performing distributed sequential node localization in active sensor deployment, comprising: an equilateral orthogonal reference frame comprising s+1 anchor nodes that is placed in unreferenced s-dimensional physical space, wherein the s+1 anchor nodes comprise s outer anchor nodes situated at fixed distances from a root anchor node located at the vertex of the reference frame; and a mobile effector to sequentially place new nodes in a natural sequential ordering within the s-dimensional physical space to form a sequentially well-connected network, wherein each of the new nodes is connected to at least s+1 of previously placed nodes, comprising: a mobility unit to move within a predefined distance to the location of one of the previously placed nodes; a telemetry interface to transmit ultrasonic signals to the previously placed nodes when at the predefined distance and to obtain ultrasonic signal responses comprising location estimates for the new node from the anchor nodes previously placed in the s-dimensional physical space; and a placement evaluator to determine a location for the new node based on the location estimates, wherein the new node is placed in the s-dimensional physical space as a new anchor node proximate to at least one of the s+1 previously-placed anchor nodes upon receipt of location estimates from at least s+1 anchor nodes and satisfactory location determination.
