Abstract
As one of the most important performance measures of Tactical Internet (TI), reliability will be paid much attention to. Most of the existing techniques assume the transmission range is constant. It is not applicable for TI, due to the limited power and wireless transmission characters, the transmission range of nodes decreases with time. In addition, mobility of nodes for tactical missions is different from random waypoint mobility for MANET. This paper considered the impact of variable radio transmission range and tactical formatting mobility, by extending MC simulation algorithm proposed by Cook to approximate the dynamic reliability of TI (Cook JL, Arsenal P (2007) Capacitated reliability for ad-hoc networks. Reliab Maint Symp 563:192–195). Reliability evaluation results show variable radio transmission range and mobility impose a significant impact on TI’s reliability. And sensitivity analysis allows the practitioner to quickly understand the interactions of the characteristics of TI, namely variable transmission range, tactical formation, limited links capacity and interference-aware routing protocol design.
