Problems solved by technology

However, malicious nodes can still enter the route by falsifying the trust level or guessing the trust threshold. In this case, there is no effective protection method, and there is no clear measurement and distribution strategy for trust

Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] Such as figure 1 , a trusted routing protocol strategy for wireless ad hoc networks based on the packet forwarding rate is as follows:

[0049] Step 1: Before sending the data packet to the destination node d, the source node s first searches its own routing table. If there is a routing table entry that meets the minimum trust value x of the data packet, that is, the path trust value is greater than x, then jump to step 3;

[0050] The routing table includes destination ID, destination address sequence number and path, wherein the path includes next hop node, hop count, path trust degree and expiration time. The destination address serial number is the latest destination address serial number known by the owner of the routing table, which indicates the freshness of the routing table entry and is used to avoid routing loops. The next-hop node i...

Abstract

The invention discloses a wireless ad hoc network credible routing protocol based on the package transmission rate. According to the protocol, a plurality of routes which meet confidence requirements are subjected to searching during a one-time route finding process, so that searching efficiency is improved; found routes are used as candidate routes through a source node, and a route with the minimum number of hop counts is selected to be used as a data package transmission route; and a hop-by-hop routing mechanism is used in the protocol, two kinds of indexes of the hop counts and the route credibility are used for route confidence evaluating, malicious nodes are effectively identified and removed, high-reliability credible routing is achieved, the route credibility is a model based on the package transmission rate, the model is simple, communication overhead is low, achieving is easy, and the model is very suitable for a wireless ad hoc network with limited bandwidth resources and computing capacity.

Description

technical field [0001] The invention relates to a wireless ad hoc network trusted routing protocol based on packet forwarding rate. Background technique [0002] Wireless ad hoc network MANET is a multi-hop self-organizing system composed of wireless peer nodes. Two peer nodes beyond the mutual communication range can only complete the information exchange through the intermediary node. Therefore, the nodes in the MANET network play the functions of host computer and router at the same time. Routing in wireless ad hoc networks faces more challenges than wired networks with a fixed topology. [0003] Existing routing protocols (such as DSR, AODV, LAR, etc.) can deal with unstable topological structures well, however, there are many shortcomings in the attack of malicious nodes. At present, for routing attacks, a reputation-based trusted management mechanism can be introduced in the routing decision-making process, which can effectively identify and exclude malicious nodes. ...
