Abstract:

A MANET is a group of wireless moblie nodes working togather to form a network without any fixed infrastructure. Two non-adjacent nodes can communicate with each other via the intermediate nodes.

The provision of QoS in MANETs requires a MAC which allows bandwidth and resource reservation for the contending flows, thereby providing some qualitative (DiffServ type service or preferential service)/quantitative (explicit reservations type service) QoS. Such reservations are difficult in a mobile scenario as links are continuously been formed and broken and the bandwith varies with the number of contending flows.

This presentation is on some mechanisms to improve channel contention and utilisation which are crucial for QoS provision in the Network.
