—In two-tier LTE heterogeneous networks (HetNets), picocells can be offered radio resource in order to mitigate interference to picocell users in downlink transmission from high-power macrocell base station (MBS). This becomes important in order to maintain efficient operation of the network and generate benefit tradeoff between macrocell and picocells. In(More)
Most existing work on path computation has been focused on the shortest-path problem, which is to find the optimal path between an origin and destination pair. To get an optimal route, they usually consider travel time moving forward on the road and distance from a source to a target as crucial factors to value and select a path. However, it is not(More)
