In this paper an attempt is made to propose an energy aware clustering algorithm for longer life of MANET; that selects an efficient cluster head with the help of Max-heap tree. The Clusters are designed using max-heap on the basis of energy level; the node which has the highest energy ...
2. Then we move forward to next element '2' in the array, we check Whether 2 is smaller than current max item in heap, which is '5', if yes, then replace 5 with 2 Then re-arrange the heap 4 / \ 2 1 3. Repeat the process for items [3,0] 3 2 / \ / \ 2 1 0 1 4....

is_heap、is_heap_util: 判断给定序列是否为堆、判断给定序列到哪个位置之前为堆。 min、max: 返回最小值、最大值。 minmax: 返回pair<min, max>。 min_element、max_element: 返回序列中第一个最小值、最大值。 minmax_element: 返回pair<min, max>,若有多个最值,返回的是第一个最值。

build heap:This function is pretty straightforward. It just runs a for loop, and keeps calling theheapify()function until the max heap is created. The second for loop in it, does something similar, but swaps the root node with the last value. ...
