Brief Announcement: Universal Data Aggregation Trees for Sensor Networks in Low Doubling Metricstatic and independent of the number of data sources and fusion-costs at intermediate nodes. The tree construction is in polynomial time, and for . topologies it guarantees a .(log..)-approximation of the optimal aggregation cost. With constant fusion-cost functions our aggregation tree gives a .(log

To improve efficiency, they are often used only when greedy approaches fail..We present protocols for connected quasi unit disk graphs, where nodes which are close to one another (distance at most .) are

Building a Communication Bridge with Mobile Hubs optimization problem where the objectives are minimizing the number of hubs on the bridge and either the maximum or the total distance traveled by the hubs. For a geometric version of the problem where the hubs must move onto the line segment [.,.], we present algorithms which achieve the minimum n

When only a few sensors can move, we would like the mobile sensors to be able to deploy immobile sensors to improve or repair the network connectivity or coverage. When
