   In ALL pattern the hierarchical addressing for the router and host nodes are shown below:

   Router      {0.0.0}       - node 0

   Host 1             {0.0.1}        - node 1

   Host 2               {0.0.2}       - node 2

   The address for the wireless sensor nodes are:

   Gateway         {1.0.0}      - node 3

   Sensor nodes         {1.0.1} TO {1.0.50}    - node 4 to 53
