Transmission Optimization Metrics Setup Issues in the Field of Time Constrained Communications

Abstract

This article introduces a new approach in the field of network optimization based on Transmission Optimization Metric (TOM), which is aimed at improving traffic flow continuity and increasing the chances for traffic flow sustainability in a way that helps to minimize inter-packet gaps. The work is mainly focused on harsh transmission conditions in narrow-band networks. Finally, the presented approach has impact on better resource allocation as fewer attempts are necessary for successful completion of a transmission. A significant part of the article deals with parameterization of coefficients used by the TOM optimization method. Examples of analysis for several topologies of narrow-band wireless networks based on CSMA/CA and TDMA protocols are used to demonstrate various issues related to proper setting of parameters. The introduced TOM metric has the potential to become a standard for optimization, for example, in sensor networks that are characterized by the specific nature of data traffic.

Verification of a new metric for data flow continuity and sustainability optimization

“…TOM, and especially the importance of proper boundary selection, is further discussed in detail in the article "Transmission Optimization Metrics Setup Issues in the Field of Time Constrained Communications." 19 Depending on the selected method, packets exceeding the defined boundaries can be considered as a source of potential risk of communication failure. This will be discussed in the following sections.…”

“…As we described in our article “Transmission Optimization Metrics Setup Issues in the Field of Time Constrained Communications,” 19 we can use two approaches to computation of IPGA: the number of packets passing through an IP connection between two consecutive packets within the monitored IP connection (see illustration of the principle in Figure 6) and the time between the arrivals of two consecutive packets within a single IP connection (see illustration of the principle in Figure 7). …”

“…As we can use the two approaches of IPGA, we can also derive two versions of TOM—one based on absolute length of packet gap boundary and the other one based on specific time boundary. TOM, and especially the importance of proper boundary selection, is further discussed in detail in the article “Transmission Optimization Metrics Setup Issues in the Field of Time Constrained Communications.” 19 …”
