Internet of things and network densification bring significant challenges to uplink *** depending on optimization algorithm enhancements is not enough for uplink *** control intercell interference,Fractional Uplink Power Control(FUPC)should be optimized from network-wide perspective,which has to find a better traffic distribution ***,traffic distribution is geographic-based,and ineffective due to tricky locating *** paper proposes a novel uplink power management framework for self-organizing networks(SON),which firstly builds up pathloss-based traffic distribution model and then makes the decision of FUPC based on the ***-based Traffic Distribution(PLTD)aggregates traffic based on the propagation condition of traffic that is defined as the pathloss between the position generating the traffic and surrounding *** show that the improvement in optimization efficiency of FUPC with PLTD can be up to 40%compared to conventional GeoGraphic-based Traffic Distribution(GGTD).

＜正＞self-organizing spatial networks are integrated and intelligent networks constituted by communication and information systems from land,sea,air and *** characteristics such as high component complexity and large scale make network performances closely related to network *** paper proposed a topology control algorithm for self-organizing spatial networks based on hierarchical network *** a cluster,neighborhood direction information is used to discover and simplify local topology;symmetry mechanism is used to guarantee two-directional connectivity.K-disjoint links between adjacent clusters are maintained by finding out optimal matching of weighted bipartite graphs formed by border nodes from contiguous *** results show the proposed algorithm can enhance performances of self-organizing spatial networks.
