Research of Multidimensional Optimization of LEACH Protocol Based on Reducing Network Energy Consumption

Table 1

The LEACH protocol running process.

Input: N sensor nodes deployed, Eo initial energy of nodes,

are 200∗ 200. Nceluster number of clusters in the network.

1  Flag_NetworkDead = 0;

2  While (Flag_NetworkDead = = 0)

3   for c = 1:Nceluster

4    Select any node for cluser head (CH) of cluster c which satisfies constraint

     a.

5    Select the best cluster head based on equations (4) and (5)

6    Received packets at CH from all child nodes and transmit to the base station (BS)

7    Update energy of all the nodes
