Abstract
Energy constraints is one of the major challenges for mobile devices, because battery is the only resource that cannot be replenished without any external provider. Computational offloading and fidelity adaptation are two common approaches which have been proposed for reducing energy consumption. It is obvious that total amount of energy consumption highly depends on energy consumption of each active resource in mobile device. Therefore, we can share a resource with high energy consumption which is needed by a set of mobile devices, via a low energy consuming connectivity protocol. Using this sharing method, we can decrease overall average energy consumption of mobile devices. Due high mobility in mobile environments, mobile ad-hoc networks are not suitable for resource sharing. In order to respond to this limitation, we use the Delay Tolerant Network (DTN) concept for resource sharing. DTN is an overlay network based on message passing through neighbouring mobile devices which is designed for responding to lack of connectivity and heterogeneity in mobile environments. In this dissertation, we prove energy saving of this resource sharing mechanism analytically using SIS epidemic models. In addition, our simulation results support the proposed mechanism for energy saving in mobile device environments.
Keywords: Mobile Computing, Energy Consumption, Resource Sharing, Delay Tolerant Networks.
