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-

As common in all societies and nations, crime is considered a heinous act that deserves punishment and condemnation from society. According to recent reports, a significant increase in the crime rate has been observed in recent years, which requires serious action in order to limit the spread of crime and maintain public security and safety. Whereas, this role of fighting crime does not only concern the competent authorities such as the police and security authorities. Rather, everyone, as a whole, must act to limit the effects of crime and restrict its spread, each according to his/her role and field of work. We should all stand together to exploit our specialization fields for combating and limiting the spread of crime. As no nation or society can get an evidence, progress or development of value with the increasing of the criminal rate. Where it is incumbent on the community to unite and cooperate in order to detect the crime, each of them according to the role assigned to and then the relevant authorities take the necessary measures and decisions regarding this case. In order to achieve this goal, as specialists in communications and informatics, our research question focuses on "What measures do we need in order to eliminate/reduce the criminal rate to a minimum?". In this study, we have focused on making the most of the applications of this IoT technology, by focusing on the human community in general. In addition to health care, personal life and public and private property. The CPS, which we propose through this study, provides an architecture of realistic model that has not been addressed before, and its contribution to enhancing security and public safety as it will be presented in this study.
