Coordinated Resource Management in Support of 
Auxiliary Services in Mobile Networks

Hany Morcos

Well-provisioned portable computing devices offer an attractive platform
for the deployment of services other than the primary services intended
for these devices. Being in the possession of users for extended periods
of time, these devices are particularly well-suited to  host "auxiliary
services" that require wide spatial coverage, and which could leverage
user mobility. A distributed service hosted on first-responders
wearable-computers to monitor levels of carbon-monoxide is an example of
an auxiliary service with such requirements. This thesis examines the
benefits from judicious coordination and control of the resources
available on mobile platforms to enable auxiliary services supporting
field monitoring and message routing applications in both wireless
sensor networks (WSN) and delay-tolerant networks (DTN). In particular,
it considers the performance benefits attained by auxiliary services
when such services are allowed to make control and coordination
decisions along a number of dimensions, including memory management, and
activity and mobility planning. It shows that: 1) mobility is a key
determinant of performance for many envisioned auxiliary services ; 2)
device mobility and storage could be efficiently managed in support of
distributed field monitoring applications; 3) a-priori knowledge about
spatio-temporal query distributions could be leveraged for improved
performance of field monitoring applications; 4) enabling nodes to
decide when and where to sample the field improves the performance of
field monitoring; 5) guiding host mobility is an effective approach to
improve performance of a number of WSN and DTN applications; and 6)
a-priori knowledge about the communication patterns in DTNs could be
leveraged in guiding host mobility for superior performance.
