Paper Abstract:
|
Effective queue management carries much significance for better congestion control and avoidance in networks like opportunistic network. However, it is quite difficult to design such management scheme for this kind of network due to mobility and absence of end to end connectivity. In this paper, a queue management scheme has been proposed for effective congestion handling. This scheme intelligently stores bundles in queues and delivers to contacting peer based on weight calculated from local information such as time-to-live and hop count and ensures bundle delivery even in overflowing traffic volume. While bundles are in queue, bundle forwarding order is regularly monitored and rearranged if necessary. Moreover, an exchange mechanism of this scheme provides the ability for a node to transfer highly preferred bundles in congested situation. Preliminary simulation results of this scheme showed effective and encouraging performance in terms of delivery ratio compared to first in first out (FIFO) scheme. |
