Mobility Metrics Based Classification & Analysis of Mobility Model for Tactical Network

Abstract

In the tactical network scenario mobile nodes are require to attain high degree of mobility without the aid of prior network infrastructure. To access the efficient and reliable communication it must be based on tactic scenario like specified area, task specified unit etc. in real time. The performance of this system in real time is very difficult to do because of it need field test, several hundred devices as well manpower. The evaluation of algorithm and protocol simulation is another alternative to evaluate the performance of tactical network. The simulative performance evaluation relies on models used in the network. This paper basically provides survey and categorization of the mobility model on account of mobility metrics, as well as analysis of those models which meet the tactical scenario requirement tabulated in table 2.

Classification and Evaluation of Mobility Metrics for Mobility Model Movement Patterns in Mobile Ad-Hoc Networks

“…The direct mobility metrics like host speed or relative speed, are measurement of clear physical behavioural meaning while the derived mobility metrics, like graph connectivity, are measurement of physical observation through mathematical modelling. A good effort of mobility models classification has been carried out based on mobility metrics taking account of above two categories and tabulated in table 1 by several studies of the literature [3,4,5,6,7,8,9,10,11,12,13,14,15,16,17 ]. …”

“…Second direction is to analyze mobility models on account of mobility metrics and influences of mobility models on routing protocols. There are many mobility models have been proposed in the literature (3,4,5,6,7,8,9,10,11,12,13,14,15,16,17). Brief descriptions of some mobility models are:…”

Data replication in mobile tactical networks

“…There is one leader or a group of leaders which tells other nodes where and how to move or in which area to work. This implies group mobility [7,8]. Furthermore, as tactical scenarios take place in areas of conflict, obstacles such as trenches or traps might be encountered.…”

The Literature Review: Performance Enhancement of Mobility Models in Wireless Ad Hoc network

“…Traces are those mobility patterns that are observed in real life systems. Traces provide accurate information, especially when they involve a large number of participants and an appropriately long observation period [10][11][12][13][14][15][16][17][18]. However, new network environments (e.g.…”
