Abstract:

The routing maintenance is often invoked in mobile Ad Hoc network because the constructed routings using topology-based routing protocols often break. Moreover , the position-based routing algorithms need neither the construction nor the maintenance of routings , but they need location service to get the position information of the destination. To solve these problems , this paper proposes a hybrid routing algorithm based on topology and position information , which can obtain the position information of some nodes in the process of routing construction without special location service. When the constructed routing fails , the source can send data packets directly through the position-based forwarding strategy if it possesses the position information of the destination. Simulated experiments show that the proposed algorithm reduces the time of routing maintenance , decreases the overhead and improves the performance of routing.
