This interactive standalone program to create routing tables for specified radios is a vast improvement over the existing testbed’s version in terms of user-friendliness. It intuitively prompts the user for relevant (destination, next hop) pairings, which are then stored in comma-separated values file (*.csv) in the /RTs/ directory. This allows easy modification of the routing tables through spreadsheet applications such as OpenOffice Calc or Microsoft Excel. In addition, a ‘priority’ field is built into the routing table to future-proof this concept. The routing table headers and layout is defined in the global variables file.

As simple routing is built into the base implementation of WiSeNeT by default, routing tables need to be manually defined for the relevant radios if routing is to be enabled on those radios. It is recommended that all possible destinations are programmed into the routing table for completeness, as the base implementation will drop a packet at the network layer if it cannot find the destination in its routing table. This implies for an n node network, there will be n-1 entries in the routing table.
