Interference-Aware QoS OLSR for Mobile Ad-Hoc Network Routing
Dang-Quan Nguyen, Pascale Minet · 2005
Ad-hoc wireless networks are made up of mobile devices that use wireless transmission for communication. They can be set up anywhere and at any time because they neither require infrastructure nor central administration. Hence they have enormous commercial and military potential. However, the bandwidth offered to users is strongly affected by radio interferences. This paper proposes a solution taking into account radio interferences at the routing level in mobile ad-hoc networks. This solution is based on an admission control and a modified version of OLSR routing protocol that considers bandwidth reservation and interferences. A comparative performance evaluation done by NS simulations shows that this solution outperforms classical OLSR in terms of maximum number of acceptable flows, bandwidth amount granted to a flow and route stability.
