CONTENTION-AWARE PERFORMANCE ANALYSIS OF
MOBILITY-ASSISTED ROUTING
A large body of work has theoretically analyzed the performance of
mobility-assisted routing schemes for intermittently connected mobile
networks.
However, the vast majority of these prior studies have ignored wireless
contention. Recent papers have shown through simulations that
ignoring contention leads to inaccurate and misleading results, even
for sparse networks.
In this paper, we analyze the performance of routing schemes under
contention. First, we introduce a mathematical framework to model
contention. This framework can be used to analyze any routing scheme
with any mobility and channel model.
Then, we use this framework to compute the expected delays for
different representative mobility-assisted routing schemes under
random direction, random waypoint, and community-based mobility
models.
Finally, we use these delay expressions to optimize the design of
routing schemes while demonstrating that designing and optimizing
routing schemes using analytical expressions that ignore contention
can lead to suboptimal or even erroneous behavior.

OPPORTUNISTIC SCHEDULING WITH
RELIABILITY GUARANTEES IN COGNITIVE
RADIO NETWORKS
We develop opportunistic scheduling policies
for
cognitive radio networks that maximize the throughput
utility of the secondary (unlicensed) users subject to
maximum collision constraints with the primary (licensed)
users.
