Problems solved by technology

However, the strategy of fixed allocation of resources is not suitable for occasions with low network traffic. In the case of low network traffic, each sending node must wait for its own time slot to arrive before sending data, which introduces unnecessary problems. Necessary delay reduces network overhead and leads to waste of resources

Embodiment Construction

[0025] 1. Set the flow threshold K 1 (upper threshold) and K 2 (lower threshold), sampling interval t seconds and damping factor α;

[0026] 2. The node takes t as the cycle, and records the number f of data packets received in the latest t time ik , f ik is the number of all data packets of flow i received in the ((k-1)*t, k*t) time period;

[0027] 3. Calculate the damping function of the data stream i, the calculation method is as follows:

[0028] p ‾ k = α × f ik + ( 1 - α ) × p ‾ k - 1 , 0 ≤ α ≤ 1

[0029] This damping function is equivalent to filtering out the high-frequency...

Abstract

The invention relates to a method for achieving dynamic resources obligating of a self organization network by using long traffic detection. The method avoids a traditional mechanism of a network node channel competition, and an important transaction and a high priority transaction can be forwarded in high reliability, the method for the dynamic resources obligating is recommended in Ad hoc network, and a channel distributed according to need is inserted into a control protocol, and network resource distribution is achieved to dynamic, and a goal for providing different resource to a different upper transaction is furthest achieved, meanwhile, the highest network transmission efficiency is kept in a station of lower network load and higher network load. The method can dynamically identify and distinct different characteristic transaction traffic in real time, and then the resource is directly obligated, and an operating factor of the channel is improved, and has high utility value.

Description

technical field [0001] The invention relates to a resource reservation technology in a wireless self-organizing network (Ad hoc), which is based on the detection results of real-time data streams by wireless self-organizing network nodes in operation, and is used for services with high priority and large data volumes. Reserving dedicated resources, adopting competitive transmission for services with low priority and small data volume, so as to realize load sharing in the wireless ad hoc network and make more effective and reasonable use of the scarce bandwidth resources in the wireless channel. Background technique [0002] The Ad hoc network originated in the 1970s, when the Defense Advanced Research Project Agency of the United States proposed the concept of a multi-hop wireless packet network PRNET (multi-hop multi-access packet radio network). The core function of the network is that the data generated by the wireless terminal can be transmitted to the destination termin...
