Power-efficient multicast routing is just one of the essential issues in the subject of mobile ad hoc networks. Multicasting is actually a phrase which means delivering data packets to several mobile nodes from an projected source. Worth of Support enlarges the assistance degree of expected performance for community systems. This research work centers around intend and progress strategy of QoS ...

WiFi offloading is becoming one of the key enablers to help the network operators dealing with the exponentially growing demand of mobile data. The idea of using WiFi to offload data traffic from cellular network has proposed for many years. However, the interoperability issue between the two networks needs to be enhanced so that WiFi can efficiently supplement for the cellular network in case ...

Our WiFi based Indoor Positioning System (IPS) – WiFiGenius, leverage the WiFi received signal strength (RSS) of mobile device mainly to achieve accurate and reliable indoor localization. We upgrade the firmware of the existing commercial WiFi access points (APs) to allow them to collect WiFi RSS of each mobile device. The RSS and MAC addresses of mobile devices are then sent to a location serv...

Bluetooth low energy(BTLE) is an emerging lowpower wireless communication technology which is expected to be of great potential in the next few years. In this paper, we propose several empirical propagation models for BTLE in different conditions: indoor/outdoor, line-of-sight (LOS) / non-line-ofsight (NLOS). Then we compare the propagation characteristics between BTLE and WiFi. It is demonstra...

Solution accuracy of global navigation satellite systems (GNSS) is often compromised by the satellite-user geometry, weak signal levels and system outages. Locata Corporation’s positioning technology potentially bridges such gaps in availability, providing cm-level accuracy in challenging positioning environments. A Locata network consists of timesynchronized terrestrial transceivers (called Lo...

With the proliferation of WiFi-enabled devices, people expect to be able to use them everywhere, be it at work, while commuting, or when visiting friends. In the latter case, home owners are confronted with the burden of controlling the access to their WiFi router, and usually resort to simply sharing the password. Although convenient, this solution breaches basic security principles, and puts ...

LTE-U/WiFi coexistence can be significantly improved by placing so-called coexistence gaps in space through cross-technology interference-nulling (CTIN) from LTE-U BS towards WiFi nodes. Such coordinated co-existence scheme requires, for the exchange of control messages, a cross-technology control channel (CTC) between LTE-U and WiFi networks which was presented recently. However, it is unclear...

WiFi Networks have been globally deployed and most mobile devices are currently WiFi-enabled. While WiFi has been proposed for multimedia content distribution, its lack of adequate support for multicast services hinders its ability to provide multimedia content distribution to a large number of devices. In this paper, we present the AMuSe system, whose objective is to enable scalable and adapti...

This paper provides a brief overview of wireless (WiFi) networks and some of the security measures in place today. We further seek to find a secure way to authenticate and enable secure communication between wireless (WiFi) clients and external networks.
