With the advancement of technology, there is a growing desire to provide support for real time multimedia services over wireless ad hoc networks. These applications demand strict Quality-of-Service (QoS) guarantees by the underlying network in terms of delay, delay variance and packet loss. However, limited battery life of the nodes in a wireless network poses significant challenges in finding QoS...
We consider the problem of supporting traffic with elastic bandwidth requirements and average end-to-end delay constraints in multihop wireless networks, with focus on source rates and link data rates as the key resource allocation decisions. The network utility maximization-based approaches to support delay-sensitive traffic have been predominantly based on either reducing link utilization, or approximation...
This work presents a self-organized message-ferrying algorithm called SOFCOM, which solves the next-hop decision problem in mobility-controlled message ferrying networks. We provide an analytic model for the single-ferry scenario, in which multiple static network nodes require transient connectivity for message exchange. Relaxing the system's state complexity allows us to compare our approach with...
