Cross-layer cooperated routing method supporting multi-speed transmission in Ad Hoc network

Abstract

The invention discloses a layer-crossing coordinating route method for supporting multiple speed rates in the Ad Hoc network, which relates to the technical field of the radio communication. The steps are following: after the high layer date generating, the network layer searching whether the data achieve the effective route of the purpose note; if the data exists, skipping to the next IP address and the delivering the data frame to the ARP layer; otherwise, the network layer builds the route according to the long-skipping route principle, delivering the next IP address and the data frame to the ARP layer; ARP layer addressing the corresponding address and data conversion to the MAC layer frame; MAC layer first node to find whether there is synergy, if there is, MAC layer MAC synergistic way of transmission, if there is, MAC layer transmitted using DCF. The invention enlarges the probability of the coordinating node by the long-skipping route principle in the building of route, and via the use of collaboration technology, will be included in each routing of a low-speed long-distance high-speed link into two shorter links, so as to more effectively support multi-rate transmission and improve network performance.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a cross-layer cooperative routing method capable of supporting multi-rate transmission in an Ad Hoc network. Background technique [0002] Wireless networks can generally be classified into two categories: infrastructure-based networks and infrastructure-less networks. Infrastructure-based networks rely on pre-deployed network infrastructure. Typical examples include cellular networks and wireless local area networks (WLANs). In order to be able to temporarily and quickly automatically form a network, a network without infrastructure is proposed, that is, an Ad Hoc network. [0003] Ad Hoc network is a temporary, arbitrary topological autonomous system composed of a group of mobile terminals with wireless transceivers. The mobile terminal is referred to simply as a network node or node. In an Ad Hoc network, the transmit power of a node is limited and generally d...

Problems solved by technology

However, these routing protocols that support multi-rate transmission require more protocol overhead to obtain the required information, and high-rate communication requires more hops to reach the destination node, which increases the number of data forwarding and the number of competition channels, thus lead to an increase in the overall delay of the network
