BRuIT is a QoS enabled routing protocol it searches route on demand, when a data flow needs a resource reservation, Each intermediate host only forwards the route if it estimates that the enough bandwidth can be supported by the network When destination host receives a route request a confirmation message is sent back by the reverse route to the source Each host periodically broadcasts a Hello message to every other node in its communication range If a node moves, breaks the route, than neighbor node sends an error message to the source that the route is broken than source broadcasts route request for new route BRuIT generates less signaling overhead and reacts quickly in case of route break due to mobility.

1. Bandwidth Estimation Mobile Ad Hoc Networks

2.  Mobile Ad-hoc network is a self configuring wireless network
 Providing (QoS) routing is a challenging task
 Time sensitive applications need quality of service guarantee therefore research in ad
hoc network mainly focuses on QoS support
 QoS in term of routing selects best route according to application requirement
APPLICATIONS:
 Military application
 Search and secure operations
 Temporary network
 Airport
 Vehicle to vehicle communication
 Public safety systems
 Electronic payment anywhere at any time

Bandwidth Reservation under Interferences Influence (BRUIT)
 BRuIT is a QoS enabled routing protocol it searches route on demand, when a data flow
needs a resource reservation,
 Each intermediate host only forwards the route if it estimates that the enough bandwidth
can be supported by the network
 When destination host receives a route request a confirmation message is sent back by
the reverse route to the source
 Each host periodically broadcasts a Hello message to every other node in its
communication range
 If a node moves, breaks the route, than neighbor node sends an error message to the
source that the route is broken than source broadcasts route request for new route
 BRuIT generates less signaling overhead and reacts quickly in case of route break due to
mobility.
