Novel routing protocol for solving congestion problem of wireless routers

Abstract

A novel routing protocol for solving the congestion problem of wireless routers can be used for information detection and transmission. The novel routing protocol is mainly composed of a link breakage strategy and a node congestion strategy. When a router in a node fails due to link breakage, the routing protocol can limit the broadcast of the invalid router in a limited range and create a new loop-free router reaching a target node based on the existing information. Thus, packet loss because of link breakage can be reduced, and the packet delivery success rate of the network can be improved. When congestion occurs to a node, the routing protocol can notify an upstream node to recreate a loop-free router reaching the target node in the same processing approach as link breakage processing. Thus, packet loss because of node congestion can be reduced, and the packet delivery success rate of the network can be improved.

Description

technical field [0001] The invention belongs to the field of wireless communication, relates to a network routing strategy suitable for information detection and transmission, specifically relates to a new routing protocol for solving the problem of wireless routing congestion, which can be used for information detection and transmission. Background technique [0002] Mobileadhocnetworks (MANETs) is a mobile ad hoc network. In such a network, the terminal coverage is limited, and two user terminals that cannot communicate directly can use other nodes to forward packets. Due to its particularity, its application occasions mainly include the following categories: military applications, sensor networks, emergency applications, personal communications, etc., and its application in sensor networks is gradually increasing. However, due to the lack of infrastructure, node mobility and unpredictable topology changes, node connections may fail. In addition, when the network traffic...

Problems solved by technology

Most people rebuild the broken route by detecting the state of the link and using information exchange strategies. This can only solve the problem of packet loss caused by link breaks but cannot solve the problem of packet loss caused by network congestion.

For the problem of network congestion, people mostly reduce network congestion by adjusting the sending rate. Although this method can reduce network congestion, it cannot efficiently utilize the entire network, resulting in waste of resources.
