Research Area:  Mobile Ad Hoc Networks
A Mobile Ad Hoc Network (MANET) is an infrastructure-less wireless network which allows a group of mobile devices to connect wireless without centralized administration. MANETs are useful when rapid deployment in infrastructure-less locations is required, or under emergency situations where communication is not available. Video conferencing over MANET is challenging due to features that characterize this type of network.
This thesis proposed an enhanced scheme based on tuning, modeling, and optimizing the Optimized Link State Routing (OLSR) protocol behavior. The objective is to overcome MANET challenges including Quality of Service (QoS), energy consumption, and security. The novelty of the proposed scheme comes through using an optimal configuration of OLSR protocol which changes the protocol behavior by modifying the HELLO and Topology Control (TC) message intervals to cope with most desirable QoS metrics for transmitting video conferencing traffic over MANET such as (end-to-end delay, Packet Delivery Ratio (PDR%), Jitter, throughput, and WLAN-load).
Also, the optimized configuration of the OLSR protocol provides low power consumption due to adaptive behavior in case of network topology changes. The power dissipated for sent/received packets dropped by 40%. The new fine-tuning of OLSR maintained QoS under two popular attacks: black hole and jamming attacks. The proposed scheme is promising for transmitting video conferencing traffic effectively over MANETs.
