Delay Tolerant Networks (DTNs) are characterized by sparse node density, uncertain node mobility and lack of global information, which make routing one of the most challenging problems. In this paper, we propose a new routing protocol for DTNs. We observe that the forwarding performance of a node is not only determined by its contact schedules with the destination but also affected by its contacts...
In wireless optical broadband access network (WOBAN), when a new session was established, some links probably overlapped the existing session, which leaded to congestion. To reduce the blocking probability in the overlapped links, a routing algorithm named ILCA (Integrated Least Congestion Algorithm) was designed. This algorithm integrated both multichannel technology at the wireless domain and wavelength...
A novel scheme entitled as Additive Increase Multiplicative Decrease control with the Number of Burst Control Packet (AIMD-NBCP) is proposed. Simulation results show that AIMD-NBCP scheme is efficient at keeping the network stable and enhancing the performance of deflection routing in terms of good-put, burst loss probability as well as fairness index.
