11.3.1 QoS Challenges in MANETs
To be able to support the real-time voice and video communications over MANETs, novel QoS
provisioning mechanisms need to be developed. However, there are many problems in providing
QoS in MANETs in comparison with static wired networks due to many reasons [4–6,56]:
◾ Interconnection between source-destination devices relies on peer wireless and mobile nodes
that operate as routers. en, rerouting among mobile nodes causes topology and network
load conditions to change dynamically, which may complicate the support of real-time
