In a mobile environment, maintaining cache consistency is challenging. Applying one type of consistency levels either strict or weak is not suitable all the time, as the consistency requirements mainly depend on the mobile application system and differ from one to another. Also forcing the mobile client to use its cache data for the purpose of reading only limits the functionality of the cachin...

Though interference is well known to be a significant burden on multiple input multiple output (MIMO) communication systems, mostly signal to noise ratio (SNR) limitations have been studied, whereas little experimental interference behavioural knowledge exist in open literature so far. In this letter we present measured simultaneous signal to interference ratio (SIR) data due to realistic termi...

This document defines a binding revocation mechanism to terminate a mobile node’s mobility session and the associated resources. This mechanism can be used both with base Mobile IPv6 and its extensions, such as Proxy Mobile IPv6. The mechanism allows the mobility entity which initiates the revocation procedure to request its peer to terminate either one, multiple or all specified Binding Cache ...

This paper reviews existing indoor and outdoor positioning technologies for mobile users, including GPS and its extensions, wireless communication-networks and others. Accuracy and limitations of these technologies and methods are examined in more detail. Furthermore, results of own investigations concerning Wireless LAN are presented. 1 CLASSIFICATION OF POSITIONING METHODS FOR MOBILE COMPUTIN...

The global popularity and rapid proliferation of smartphones and other types of mobile devices has greatly expanded the amount of mobile data traffic throughout the wireless cellular network. Research studies from Mobile Experts, Cisco VNI and Ericsson have shown that global mobile traffic reached 1,000 petabytes per month and is projected to grow multi-fold in the coming years. This is a signi...
