Abstract

The invention relates to a method for improving the message capacity of a mobile ad-hoc network by the combination of the link layer messages, belonging to the computer communication field. The method includes that firstly, the newly-produced network layer message is added into the different buffer queues of a sending buffer at the sending terminal according to the next hop address and the network layer message is combined with the message at the tail of the former queue and processed according to the length of the network layer message or is stored as an opposite message; when the received link layer message is extracted at the receiving terminal, the data length of the link layer is compared with the length of the network layer message and then judged, and each network layer message extraction is completed through cyclic processing. With the method of the invention, only little modification to the current protocol stack can help obviously improve the message capacity in the mobile ad-hoc network under high busy state; the method has the advantages of simple computation, small computation complexity and easy achievement.

Description

technical field

[0001] The invention belongs to the field of computer communication, and in particular relates to the communication capacity problem in the mobile ad hoc network based on the asynchronous media access control protocol. Background technique

[0002] Mobile Ad hoc Network (MANET for short) is a wireless network that utilizes multiple hops between wireless nodes to achieve large-scale communication. It is independent of infrastructure, self-organizing, and multi-hop routing. A novel wireless networking method.

[0003] The mobile ad-hoc network is composed of nodes with the function of storing and forwarding messages: this is similar to the functions of core nodes in traditional wired packet networks, such as routers and switches, where the storage and forwarding of messages involves the network layer The sending buffer management between the link layer and the sending buffer management has the functions of: 1) storing messages from the network layer; 2) sendin...
