Networked Software Systems Laboratory Department of Electrical Engineering Technion 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 (facts)

Networked Software Systems Laboratory Department of Electrical Engineering Technion 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 with corresponding routing protocol. Dynamically alter the routing tables used by routers.

Networked Software Systems Laboratory Department of Electrical Engineering Technion 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] }
