Cooperative Coded Data Dissemination for Wireless Sensor Networks

In this poster paper we present a data dissemination transmission abstraction for over the air programming (OAP) protocol which is fundamentally different from the previous hop by hop transmission protocols. Instead of imposing the greedy requirement that at least one node in the ith hop receives all packets before transmitting packets to the next hop and its neighbours, we take advantage of the spatial diversity and broadcast nature of wireless transmission to adopt a cooperative approach in which node broadcast whatever packets it has received with the expectation that it will recover the lost packets with high probability by overhearing the broadcast transmissions of its neighbours. The use of coded transmissions ensures that this does not lead to the broadcast storm problem. We validate the improved performance our of proposed transmission scheme with respect to the previous state of the art OAP protocols on a proof-of-concept two-hops TelosB wireless sensor network testbed.Comment: This paper appears in: 2016 13th Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), London, 2016, pp. 1-

Noncommutative Geometry: Fuzzy Spaces, the Groenewold-Moyal Plane

In this talk, we review the basics concepts of fuzzy physics and quantum field theory on the Groenwald-Moyal Plane as examples of noncommutative spaces in physics. We introduce the basic ideas, and discuss some important results in these fields. In the end we outline some recent developments in the field.Comment: This is a contribution to the Proc. of the O'Raifeartaigh Symposium on Non-Perturbative and Symmetry Methods in Field Theory (June 2006, Budapest, Hungary), published in SIGMA (Symmetry, Integrability and Geometry: Methods and Applications) at http://www.emis.de/journals/SIGMA

Mitigating Risk of Failure by Expanding Family Entrepreneurship and Learning from International Franchising Experiences of Johnny Rockets: A Case Study in Pakistan

It is generally believed worldwide and backed by research too that startups face a high risk of failure and eight to nine out of ten ideas may not work (Hisrich, Peters, & Shepherd, 2009). However, many experts claim that the situation can turn vice versa for family entrepreneurship (or creative family businesses) and franchise ventures (Francorp, 2016). This exploratory probe aims to discover these two phenomena for Johnny Rockets (JR) Pakistan, which is an international franchise of fast food chain of restaurants, and simultaneously it is a family business extension. Literature is reviewed from four perspectives: family entrepreneurship and business, franchise business, internationalization of companies, and fast food restaurant industry in Pakistan. Primary data is garnered from three sources: in-depth interviews from middle to top management of Johnny Rockets, owners of the franchises, and from its consumers in accordance with phenomenology method and purposive sampling to analyze their lived experiences with JR and its direct rivals. The data analytic techniques comprise thematic analysis and constant comparison. The findings unveil that in the wake of tolerating several difficulties, now Johnny Rockets seems to be on the right path of sustainable growth. The study underpins the notions that family entrepreneurship and franchise ventures enjoy a high probability of success, but it requires an organizational culture of the congenial work environment, and propensity to create a customer-centric modern learning organization, ready to accept trials and errors and continuously innovating its processes and systems
