Abstract: | Numerous routing protocols have recently been developed for ad hoc mobile networks. Routing protocols to date can be categorized
as either ‘table-driven’ or ‘on-demand’. Many of the proposed routing protocols take the on-demand approach because this does
not require keeping lots of routing information. However, these kinds of protocols are not able to react fast enough to maintain
routing. In this paper, we propose a new protocol to improve existing on-demand routing protocols by constructing multiple
backup routes; when the network topology changed, the proposed protocol could transmit data packets dynamically through backup
routes. We then developed an analytic model to estimate the reconnection probability of the proposed algorithm. We also examined
the performance by simulating the protocol using ns2. The experimental results showed that the protocol had fewer control
packages, lower routing packet overhead, and a higher receiving ratio than others. |
