Abstract:
Guaranteeing the respect of the deadline on the end-to-end transmission delay for a hard real time traffic is a big challenge, especially in mobile Ad hoc networks. In fact, in such networks, the movement of the nodes can lead to the breakage of the current path between the source and the destination and therefore the establishment of a new path which may provide a transmission delay that exceeds the deadline. In this paper, we propose a delay prediction approach which allows guaranteeing the respect of the deadline regardless of the used path for cyclic mobility models. Indeed, we aim to predict all the possible paths between two nodes and calculate the end-to-end transmission delay in the worst case. Thus, we can guarantee the respect of the deadline if this latter is superior to the calculated delay. By comparing the worst end-to-end delay values calculated by our prediction approach with the delay values obtained by the network simulator NS2 (Network Simulator 2) for the same network, we perceive that the NS2 delays are always lower than the end-to-end transmission delay of the worst case calculated by our approach. This proves that our prediction approach allows guaranteeing the respect of the deadline on transmission delays for hard real time applications.
