The lowest cost path is always used unless the other path is down.

除非不可用，否则代价最小的路径总是被使用。

In this paper we bring forward a new resource detection algorithm based on ant colony algorithm. It takes account of certain factors such as path load, delay and finds lowest cost resources.

论文提出了基于蚁群算法的新的资源发现算法，在查找资源的同时，综合考虑路径载荷、延时等因素，找到综合费用最低的路径。

The new protocol finds the path to the cluster head with the minimum cost, using an algorithm similar to flooding to propagate the cost information and greedy algorithm to find the lowest cost link;

节点根据能量消耗的代价来选择至簇头的路由，通过扩散算法来广播代价消息，采用贪婪算法来选择能量消耗最小的路径；
