Abstract:
A Mobile Ad Hoc Network (MANET) comprises mobile nodes (MNs), equipped with wireless communications devices; which form a temporary communication network without fixed network infrastructure or topology. The characteristics of MANET are: limited bandwidth; limited radio range; high mobility; and vulnerability to attacks that degrade the signal to noise ratio and bit error rates. These characteristics create challenges to MANET routing protocols. In addition, the mobility pattern of the MNs also has major impact on the MANET routing protocols. The issue of routing and maintaining packets between MNs in the mobile ad hoc networks (MANETs) has always been a challenge; i.e. encountering broadcast storm under high node density, geographically constrained broadcasting of a service discovery message and local minimum problem under low node density. This requires an efficient design and development of a lightweight routing algorithm which can be handled by those GPS equipped devices. Most proposed location based routing protocols however, rely on a single route for each data transmission. They also use a location based system to find the destination address of MNs which over time, will not be accurate and may result in routing loop or routing failure. Our proposed lightweight protocol, ‘Local Area Network Dynamic Routing’ (LANDY) uses a localized routing technique which combines a unique locomotion prediction method and velocity information of MNs to route packets. The protocol is capable of optimising routing performance in advanced mobility scenarios, by reducing the control overhead and improving the data packet delivery. In addition, the approach of using locomotion prediction, has the advantage of fast and accurate routing over other position based routing algorithms in mobile scenarios. Recovery with LANDY is faster than other location protocols, which use mainly greedy algorithms, (such as GPRS), no signalling or configuration of the intermediate nodes is required after a failure. The key difference is that it allows sharing of locomotion and velocity information among the nodes through locomotion table. The protocol is designed for applications in which we expect that nodes will have access to a position service (e.g., future combat system). Simulation results show that LANDY`s performance improves upon other position based routing protocols.
