Abstract From the Canadian patent

A system and method for detecting communication requirements in a network (100) and placing nodes (102, 107) in various stages of activity where conditions allow. The system and method provides an algorithm to detect changes in node activity levels and alter operations such as update , transmissions and route selections based upon changes detected. In , particular the algorithm determines activity level at a node (102 107) at , each routing update interval based on factors such as a number of new destinations the node can reach, a number of route modifications that the node (102, 106) can implement, a number of routes from the node whose lengths have changed and a number of …
