Performance Research of an Improved Hybrid Routing Protocol

With the expansion of the network scale, especially in the case of frequent movement of network nodes, the network topology of the wireless ad hoc network also changes frequently, so more efficient routing becomes a research hotspot of large-scale networks. The design of inter-domain and intra-domain routing protocols in regional routing protocols has a huge impact on network performance. Due to the large overlap of intra-domain area of hybrid routes, large routing overhead and repeated pathfinding between domains, this paper improves the intra-domain routing mechanism and intra-domain routing mechanism of the traditional ZRP protocol based on the large-scale wireless ad hoc network of high-speed mobile scenarios. Different from other protocols to optimize the routing mechanism itself, this paper will establish a multi-center intra-domain routing area based on the neighbor connection degree in order to greatly reduce network overhead. And it establishes adaptive routing based on link quality in the inter-domain routing mechanism. This paper analyzes the performance of the improved routing protocol NA-ZRP through NS2 simulation. The results show that the NA-ZRP protocol can better adapt to the large-scale high-speed mobile wireless ad hoc network scenario than the traditional ZRP.
