Abstract:
1. A node for use in a wireless sensor network, comprising: memory configured to store a routing table specifying at least one data route through the wireless sensor network; and logic configured to track time and to automatically purge entries of the routing table based on the tracked time thereby forcing a rediscovery of data routes for the purged entries, wherein the logic, for each entry of the routing table, is configured to simultaneously disable, in response to user input, automatic routing table purges that are based on the tracked time while permitting the entries to be automatically updated by the node to indicate data routes through the wireless sensor network that are newly discovered by the node based on network messages communicated through the node, wherein the logic is configured to insert into at least one entry of the routing table at least one address of at least one message received by the node while the automatic routing table purges are disabled for at least the one entry.
