LEACH是一种分层的协议，其中大多数节点发送到簇头，和簇头聚集和压缩数据，并将其转发到基站（汇）。每个节点使用随机算法在每一轮以确定它是否会成为簇头在这一轮。 LEACH假定每个节点具有强大到足以直接到达基站或最近的簇头的无线电，但是，使用这种无线电以全功率的所有时间将浪费能量。对已集群头节点不能成为簇头再次用于P轮，其中P是簇头所需的百分比。此后，每个节点具有成为簇头在每一轮一个1 / P的概率。在每一回合结束时，每个节点是不是一个簇头选择最接近的簇头，并加入该集群。簇头，然后在其集群中的每个节点发送其数据创建一个日程安排。

This a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functions. The code consists of three simple classes: 1) Calc - which does the main calculations, 2) Stack - which is used to push and pop intermediate operators and numbers and 3) Symbol Table. The symbol table is a collection of calc symbols, a type structure consisting of various elements, including the expression name, function name, and the final value of the expression The evaluation procedure is done in three steps: 1) simplify the expression by removing all the elements within () and storing them in subexpressions within the symbol table. 2) Each of these sub expressions are then converted to RPN format (Reverse polar notation) and evaluated 3) Finally, the main expression is converted to RPN and evaluated-This is a simple demo of how to evaluate mathematical expressions in text format, including provision for variables and functi
