Most of the wireless multimedia applications require strict QoS guarantee (e.g. delay, bandwidth) during the communication between a single source and multiple destinations. This gives rise to the need for an efficient multicast QoS-routing strategy. Determination of such QoS-based optimal multicast routes boils down to a multi-objective optimization problem, which is computationally intractable in polynomial time. We propose a new multicast tree selection algorithm based on non-dominated sorting technique of the genetic algorithm to simultaneously optimize multiple QoS parameters. Simulation results demonstrate that the proposed algorithm is capable of discovering a set of QoS-based near optimal, non-dominated multicast routes within a few iterations. From this set the user can choose desirably favorite solution depending on specific QoS requirements. The scalability and the performance of the algorithm with increasing number of network nodes is also presented.","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference.

The performance models include the registration process of a mobile host from which a previous foreign agent receives a binding update message. When the previous foreign agent receives the binding information, it transmits the buffered packets to new care-of address of a mobile host. The two stages queuing network model is suggested. The first stage models a queue at the new foreign agent that represents the traffic for the request of the registration process generating during handoffs from mobile hosts. In the second stage a queue at the previous foreign agent represents the traffic for binding update messages and also represents the traffic destined to mobile hosts at the previous foreign agent. Therefore, in the second stage it is modeled with a queue having 2 priorities. It is shown that the queuing network model is compatible with the simulation model. Finally, it is shown that at the foreign agent traffic characteristics, host mobility, registration process time and buffer management scheme have a critical impact on the performance of mobile IP.","PeriodicalId":159750,"journal":{"name":"Vehicular Technology Conference.
