@conference {Sabir2013, title = {Design of an annular ring Ferry-assisted topology for Wireless Sensor Networks}, booktitle = {Proceedings of 2013 6th Joint IFIP Wireless and Mobile Networking Conference, WMNC 2013}, year = {2013}, note = {cited By 0}, abstract = {To ensure connectivity in highly sparse Wireless Sensor Networks (WSNs), we consider a Ferry-assisted Wireless Sensor Network (FWSN). In our FWSN, message ferries moving along concentric annulus collect the static sensors generated packets and propagate them throughout a ferry-to-ferry forwarding schema to the sink. Moreover, a ferry may embed a sensor and then could be assimilated to a mobile sensor node generating its own data. We provide a mathematical framework based on queuing theory to model the network and analyze its performances in terms of end-to-end throughput. Some of our findings are the characterization of the forwarding queues{\textquoteright} stability and the average end-to-end throughput as well. At stability, we notice a special feature where the average end-to-end throughput becomes independent of the choice of the weighted fair queuing. {\textcopyright} 2013 IEEE.}, doi = {10.1109/WMNC.2013.6548984}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84881399979\&doi=10.1109\%2fWMNC.2013.6548984\&partnerID=40\&md5=db7991dded90e289f75582cf59d1e214}, author = {Sabir, E.a and Kobbane, A.b and Koulali, M.-A.c and Erradi, M.b} }
