Advanced Networking Assignment: Context-Aware Services and Techniques

This report delves into advanced networking concepts, specifically focusing on context-aware services and positioning techniques. It begins by outlining five key context-aware services: physical sensors, virtual sensors, combined sensors, direct user input, and social media integration, highlighting their roles in capturing and utilizing contextual data. The report then explores various positioning techniques, including call of origin, Angle of Arrival (AoA), Received Signal Strength (RSS), Time Difference of Arrival (TDOA), and trilateration, which are crucial for determining location within a network. The report references Cisco documentation and a Springer publication to support the information provided, providing a comprehensive overview of these essential networking concepts.

Five popular context aware services:
 Physical sensor: Enables the feature of capturing of the physical data of the movement of
the entity.
 Virtual Sensor: Can access virtual information such as accessing data from some device
or application.
 Combined sensor: Provides information after merging of information from two or more
sources(Support,Engine & Guides, 2018).
 Direct user input: It is an alternative way of context interface; here the user directly gives
some contextual information.
 Social media: Enables exchange of contextual data between the users and the online
applications. The social media covers all the sectors of application including online
market place and e-business.
Special positioning techniques:
Call of origin: It is the simplest form of mechanism for finding the approximate position
in the RF based system.
Angulations: Known as Angle of Arrival (AoA). The determination of the position of the
mobile location in this system is done by analyzing the angle of incident of the arriving signal.
RSS: It is known as Received Signal Strength. It can be determined by the mobile device
or the receiving signal.
TDOA: Time Difference of Arrival is a wireless technology that depends on the receiving
signal coming from the call towers for determination of the location of the mobile.

2ADVANCED NETWORKING
Trilateration: It is a method of location calculation based on the Wi-Fi service
(SpringerReference 2018). The determination of the quadrant of the location is based on the
number of access points.
All the techniques mentioned above are the indoor positioning of the network.
