Abstract (facts)
•The Internet communication speed is not as fast as we would like it to be.
• Internet routing protocols today do not take into account information
about the dynamic changed load on the network routers.
• Load information can be gathered in real-time and the network can
improve the network routing according to this information.

Abstract
We would like to present a partial
solution for improving Internet routing by
altering Internet route tables dynamically,
corresponding to the routers’ load in the
Internet Network.
We suggest:
To use a simplified prototype of
Wireless Sensor Network (WSN) by
using an add-hoc standard with MAC
802.11 with corresponding routing
protocol.
Dynamically alter the routing tables
used by routers.

How Does It Work?
Routers nodes
WSN nodes
Central Station node
Link objects
Monitor objects

How Does It Work?
Router nodes:
•Creation of nodes’ list for router stations.
•Number of routers in the network: NUM_OF_ROUTERS.
for {set i 0} {$i < $NUM_OF_ROUTERS} {incr i{ }
set node_ROUTER($i) [$ns_ node]
}
WSN nodes:
•Creation of nodes’ list for WSN stations.
•Number of WSN stations: val(nn).
•Central station isn’t included.
for {set i 0} {$i < $val(nn)-1 } {incr i{ }
set node_WSN($i) [$ns_ node]
}
