A DEVICE-TO-DEVICE SERVICE SHARING MIDDLEWARE FOR HETEROGENEOUS WIRELESS NETWORKS
StatisticsView Usage Statistics
Wireless devices with diverse capabilities are ubiquitous and will continue to flourish for the next foreseeable future. There is heterogeneity with respect to capabilities as well as wireless transmission technology used. A critical issue to address in the face of growing wireless device usage is the increasing lack of spectrum and wireless resources. Sharing the wireless resources and bandwidth is considered by many to be a reasonable approach to the spectrum scarcity problem. This thesis describes a system where users may share wireless services with other users in a seamless manner. We develop a smart phone application for service sharing. By using the application as a middleware, users can get more work done via sharing, increase the spectrum utilization, create their own private network without a centralized infrastructure and offload network traffic to a less congested network path.We present architectural details of a smart-phone application and offer various ways one can implement such a wireless service sharing framework. Our application may pave way for a model in which users can sell their own services to other end users and establish a device-to-device service sharing market beneficial to the entire user set.
