Abstract
Due to its good extendibility and robustness, Ad hoc network has been widely used in various aspects. However, its performance is restricted by the mobility, limited bandwidth and centerless architecture. In order to improve the performance of Ad hoc network, this paper proposes a cross-layer Hexagonal Clustering, Position and Time slot based (HCPT) protocol, in which clusters and time slots are divided according to the geographical location. And furthermore, an effective algorithm to find routes through the geographical locations of cluster heads is proposed, which can greatly reduce message collisions and reduce network overhead. By doing simulations in the Network Simulator 2 (NS2) software, we found that the HCPT protocol shows better performance in network topology discovery compared with the Optimized Link State Routing (OLSR) protocol. Simulation results also show that the proposed scheme outperforms the standard OLSR and the improved OLSR algorithm, which is proposed by N. Harrag, in terms of routing overhead and packet delivery ratio.
