Exploring long lifetime routing (LLR) in ad hoc networks
In mobile ad hoc networks, node mobility causes links between nodes to break frequently, thus terminating the lifetime of the routes containing those links. An alternative route h...

Speeding up the evaluation of multimedia streaming applications in MANETs using HMMs
Mobile ad-hoc networks (MANETs) present quite large packet loss bursts due to mobility. In this work we propose two models based on hidden Markov models for estimating packet arri...
