Along with the reactive routing algorithms of mobile ad hoc network (MANET), preemptive routing is a patch method which tries to warn the source node and to tell it to change route in time before a link is about to break Preemptive method was proposed to decrease packet losses and improve TCP performance in MANET. However, the precision of warning occasion is an important problem, and affects TCP...
In the reactive routing algorithms of mobile ad hoc networks (MANET), preemptive routing method tries to warn the source node and to tell it to change route in time before a link is about to break. This method alleviates the problem from packet losses, and shortens the delay of route change after a route failure. However, it also decreases the number of route error packets which play an important...
Hosts in mobile ad hoc networks (MANET) are capable of self-configuration and they can migrate at will, which makes the network topology highly dynamic. Thus, routes may break easily since the data session fails when one node moves out of the sensing range of its partner. Besides that, if overused, nodes tend to drain their power completely due to the limited battery life. That will result in a short...
