The wireless multihop to an access point model appears to be a promising component of future network architectures, including multihop cellular networks and wireless access networks at the edges of mesh networks. Sophisticated software radios and core network protocols are being developed to support the integration of heterogeneous air interfaces within these access networks. A key challenge is managing...
We have formed the STARS Alliance to address alarming declines in computing enrollments and the need to broaden participation in computing. Our innovative STARS Leadership Corps engages college students in a community dedicated to giving back, persevering, and striving for excellence. The successful Corps model incorporates best practices in recruiting and retention in computing, including student...
The wireless multihop to an access point model appears to be a promising component of future network architectures, including multihop cellular networks and wireless access networks at the edges of mesh networks. Sophisticated software radios and core network protocols are being developed to support the integration of heterogeneous access networks. A challenge is managing diverse resources at access...
The approximately 10 year history of mobile payment services is characterized by numerous failures and promising but yet uncertain future. Against this background we take a look at why a dominant design has not emerged for this payment services market in Finland, despite dozens of efforts and continuous user interest even when necessary technologies, competencies, attitudes, regulation and opportunities...
The calculation of path cost is a critical component of route discovery for network routing. The criteria used to represent path cost guides resource consumption in the network. In this paper, we describe our approach, a set of protocols based on our Multiple Metrics Routing Protocol (MMRP) for integrating hop count, energy consumption, and traffic load into the path cost calculation for ad hoc or...
Although demand for computing-related jobs is rising, enrollments in computing programs have been steadily dropping for the last 5 years. Participation by women and underrepresented minorities has also been declining. We have formed the STARS alliance to address the need to broaden participation in computing. Our innovative STARS leadership corps (SLC) engages college students in a community dedicated...
Energy aware routing protocols are consistently cited as efficient solutions for ad hoc and sensor networks routing and data management. However, there is not a consistent approach to define the energy related cost metrics that are used to guide the routing protocol performance. This paper provides a survey and analysis of energy related metrics used for ad hoc routing. First, the most common energy...
Future network architectures for mesh networks, sensor networks, and hybrid networks include multiple wireless hops with fixed or mobile routers relaying messages between mobile nodes and access points. The vast literature on routing for ad hoc networks is applicable for route discovery between a mobile node and an access point for these multi-hop networks. However, most ad hoc routing protocols rely...
