Information raining and optimal link-layer design for mobile hotspots

Information Raining for Mobile Hotspots in 4G Wireless Networks

A system architecture is proposed to support mobile hotspots. The proposed architecture uses multiple repeaters to relay signals from access routers to vehicles and vice versa. Erasure codes are used in the access router to decompose data packets into fixed size fragments. The fragments are then disseminated to the vehicle through the repeaters. The original packet is reconstructed in the vehic...

DISSERTATION Link Error Analysis and Modeling for Cross-Layer Design in UMTS Mobile Communication Networks

Particularly in wireless mobile communications, link errors severely affect the quality of the services due to the high error probability and the specific error characteristics (burst errors) in the radio access part of the network. In this thesis it is shown that a thorough analysis and the appropriate modeling of the radiolink error behaviour is essential not only to evaluate and optimize the...

Cross Layer Design for Power Control and Link Availability in Mobile Adhoc Networks

Frequent changes in network topology due to mobility and limited battery power of the mobile devices are the key challenges in the adhoc networks. The depletion of power source may cause early unavailability of nodes and thus links in the network. The mobility of nodes causes frequent routes breaks and adversely affects the required performance of the applications. We propose a cross layer desi...

Link Error Analysis and Modeling for Video Streaming Cross-Layer Design in Mobile Communication Networks

severely affect the quality of the services due to the high error probability and the specific error characteristics (burst errors) in the radio access part of the network. In this work, we show that thorough analysis and appropriate modeling of radio-link error behavior are essential to evaluate and optimize higher layer protocols and services. They are also the basis for finding network-aware...
