In this paper, important aspects of the controller placement problem (CPP) in Software Defined Mobile Networks (SDMN) are discussed. To find an efficient and optimal controller placement, we must clarify how many controllers we need, where we place them in topology, and how they interact with each other. We take into consideration reliability, latency,… (More)
This volume contains the proceedings of the 2014 International Advanced Intrusion Detection and Prevention (AIDP'14) Workshop, held in Marrakesh, Morocco, on the 5th of June 2014, in conjunction with the 29th IFIP TC-11 SEC 2014 International Conference.

Why: Radio spectrum is inefficiently used. Smarter schemes: Dynamic spectrum access (DSA) A Primary User (PU): licensed user A spectrum hole: spatiotemporally unused frequency band Why: Radio spectrum is inefficiently used.

In this paper, we propose a novel mobile positioning algorithm based on estimation of radio propagation environment in cellular networks. Accurate and effective mobile positioning is imperative for successful location based services (LBS). Since radio propagation characteristics vary in different environments, knowing the environment of the mobile user is… (More)
Due to the proliferation of the multimedia applications over unreliable medium like wireless networks, robust image and video communication have become more important. In this paper, we consider the transmission distortions on the multimedia data due to both channel impairments and instant node failures for Wireless Multimedia Sensor Networks (WMSN). Two… (More)
