The Multi-Path Transmission Control Protocol (MPTCP) is the new concurrent multi-path transfer extension for the widely-deployed Transmission Control Protocol (TCP). Of course, having multiple and possibly highly dissimilar paths for transmission is a challenge for the management of the send and receive buffers, since optimal throughput is desired with a reasonable allocation of the limited memory...
TDMA is an ideal choice for solving the data collision in underwater acoustic communication networks, but it needs the global clock synchronization, which is hard to realize in underwater environment. Further, the asymmetrical energy consumption of the main node and the sub nodes will reduce the network lifetime. To address these problems, we presented a relative clock based and energy sense MAC protocol...
The resource efficiency and dependability of a trust system are the most fundamental requirements for any wireless sensor network (WSN). However, existing trust systems developed for WSNs are incapable of satisfying these requirements because of their high overhead and low dependability. In this work, we proposed a lightweight and dependable trust system (LDTS) for WSNs, which employ clustering algorithms...
This paper presents an FPGA-based design and implementation of TCP packet reordering for multiple TCP connections. In the packet processing, two FIFOs are used to preserve the packet header information and data information, respectively. The reordering process is based on the sequence and command information which can be used to determine where and how many to store the coming disorder packet or just...
As authentication provides crucial online identity, it is the basis of data security. In this paper, a session based authentication is proposed and the long unique un-guessable session identifier is used as a parameter of an authentication token. It has the advantages of one-timeness, short-lived and no prior knowledge requirement. The session model is established with detailed implementation of communication...
For low-cost RFID systems, the design of passive tags is a key issue in anti-collision protocols where lower power consumption allows a longer working distance between tags and the reader. In this paper, we look at anti-collision protocols in tags' processing for their power optimization. We propose a new criterion, which takes into account both energy consumption and time complexity, to evaluate...
