Besides the high query success rate , SCUS makes sure that the nodes are uniformly employed as storage nodes , therefore to maximize the lifetime of network.The computation and prediction of target trajectories is a significant part of target tracking problem .

SCUS算法在保证快速获取目标信息的同时还尽量均匀使用节点，以最大化网络的连通寿命。目标轨迹计算与预测是目标跟踪的一个重要内容，这方面已经有了很多成熟的工作。
