196 ◾ Mobile Ad Hoc Networks: Current Status and Future Trends
7.4 Conclusions
MANET routing is a key aspect in the development and eventual success of mobile ad hoc
networking. Its original purpose was oriented just to provide the minimum service in emergency/
military situations where any other infrastructure network (fixed or wireless) was not feasible. is
technology must now adapt its operation to much more commercial applications whose users
demand QoS levels that must be close to the ones of the infrastructure networks.
However, the dynamic nature of MANETs makes it extremely difficult to achieve the afore-
