The ever increasing video demands from mobile users have posed great challenges to cellular networks. To address this issue, video caching in radio access networks (RANs) has been recognized as one of the enabling technologies in future 5G mobile networks, which brings contents near the end-users, reducing the transmission cost of duplicate contents, meanwhile increasing the Quality-of-Experience...
RPL is specifically designed for Low power and Lossy Networks (LLNs). With the expansion of LLNs applications, security of RPL becomes one of the major concerns. This paper mainly addresses the security aspect of RPL. We first analyze the vulnerability of RPL self-organising properties, and identify a new RPL internal intrusion, named routing choice (RC) intrusion. We specially analyze the harm of...
In Delay Tolerant Networks (DTNs), how to transmit data efficiently is one of the most important issues. Recently, Random Linear Network Coding (RLNC) is proposed as a promising approach to improve data transmission efficiency in DTNs. To facilitate the development of deployment of RLNC based routing protocols, it is imperative to quantify the performance gain brought by RLNC in a rigorous and systematic...
