Heterogeneous small cell networks (HetSNet) comprise several low power, low cost (SBSa), (D2D) enabled links wireless-fidelity (Wi-Fi) access points (APs) to support the existing macrocell infrastructure, decrease over the air signaling and energy consumption, and increase network capacity, data rate and coverage. This paper presents an active user dependent path loss (PL) based traffic offload...

Recent research on intrusion detection systems (IDSes) has mainly focused on improving the traffic analyzing rate to meet the increasing bandwidth requirements [4], [5]. This has prompted the rise of hybrid usage of CPUs and GPUs well as FPGA/ASIC-based IDS systems that scale well to tens of Gbps of the ingress traffic rate [2], [3], [6]. One noticeable concern with these systems, however, is t...

Traffic offloading is a promising technique to alleviate the traffic load in LTE core networks. Based on 3GPP “SIPTO” (Selected IP Traffic Offload) architecture, this paper proposes dynamic SIPTO mechanism (D-SIPTO) for traffic offloading in LTE HeNB networks, which combines fast fourier transform (FFT) based IP traffic classification scheme (FFTTCS) with the dynamic traffic offload path select...

Offloading cellular traffic through mobile social networks has arisen as a promising way for relieving cellular networks. Prior studies mainly focused on caching data in a number of pre-selected helpers. However, such a strategy would fail when mobile users enter and leave the target area over time. In this paper, we examine the research decisions and design tradeoffs that arise when offloading...

The appearance of smartphones and increasing popularity of various mobile applications and services have caused the explosion of mobile data traffic. To avoid overloading the cellular networks, different offloading solutions (such as WiFi networks or femtocells) have been proposed and adopted. Recently, offloading cellular traffic through opportunistic communications among mobile phones becomes...

Wi-Fi technology has always been an attractive solution for catering the increasing data demand inmobile networks because of the availability ofWi-Fi networks, the high bit rates they provide, and the lower cost of ownership. However, the legacyWiFi technology lacks of seamless interworking betweenWi-Fi and mobile cellular networks on the one hand, and between Wi-Fi hotspots on the other hand. ...

WiFi offloading has been recently proposed as a cost-effective solution for coming up against the unprecedented increase in the mobile data traffic volume. However, apart from reducing the operational costs of a network operator, WiFi offloading can be also promoted as an alternative low-cost access service for users with low willingness-to-pay. In this paper, we consider a monopolistic scenari...
