Abstract:
Background: To satisfy the battle need, the information transmission delay of Mobile
Ad Hoc Networks (MANETs) which are the neural network and information transmission channel
for the modern battlefield must be lower. Therefore, the design of low-delay routing algorithms is
of great significance for improving the operational capabilities of wide-area directional MANETs.
The traditional routing algorithm design is mostly based on OSI/RM model, not on the global optimization,
resulting in the algorithm not having adaptability and performance being far from optimal.
Objective: An algorithm named MNCR (MAC and Network Cross-layer Routing) based on crosslayer
optimizing was proposed, which can finish the end-to-end data transmission with lower delay
for some particular application like wide-area directed mobile ad hoc network (MANET) for a
cooperative strike.
Methods: The proposed MNCR algorithm selected the shortest routing path based on the SDMA
(Space Division Multiple Access) timetable applied and informed by MAC. When a packet arrived,
the node computed all the possible paths and the corresponding delay according to the
SDMA timetable and then selected the path with the lowest delay, which ensured that the packets
were transmitted to the destination.
Results: The theoretical analysis shows that the MNCR algorithm is less expensive than the classical
shortest path algorithm. The simulation results show that the MNCR routing algorithm can
save the end-to-end delay and ensure the real-time transmission of information. At the same time,
the algorithm effectively balances the load of network nodes and overcomes the problem that the
shortest path algorithm is prone to the "bottleneck effect", which can effectively improve the reliability
of information transmission.
Conclusion: The proposed MNCR algorithm can finish the end-to-end data transmission with
lower delay. So it has certain particular applications in wide-area directed mobile ad hoc networks
(MANET) for cooperative strikes.
