    QUIC Protocol Performance in Wireless Networks
    (Institute of Electrical and Electronics Engineers Inc., 2018) Kharat, P.; Rege, A.; Goel, A.; Kulkarni, M.
    Google's Quick UDP Internet Connections QUIC transport layer protocol was developed in 2013 as a successor to its own SPDY networking protocol, which itself led to the formation of the HTTP/2 standard. QUIC's main motives were to take the advantages of TCP/IP and HTTP/2, and build them over UDP, in terms of reliability, flow control, and congestion control. The primary objective of this paper is to explore QUIC functionalities to suggest techniques to improve throughput, speedup and efficiency in wireless networks. The experimental results were established on a local test bed setup connected to a wireless access point in a campus network environment. Experimental results show that QUIC performance in the form of throughput and speedup over TCP/IP in live network environment. The fairness of QUIC in competing flow situations is also examined, and found to perform well in long life traffic. We also propose the reintroduction of FEC for minimization of retransmission latencies. © 2018 IEEE.

    Key Pre-distribution Scheme for Wireless Sensor Networks Using Combinatorial Design
    (Springer Science and Business Media Deutschland GmbH, 2022) Kittur, L.J.; Pais, A.R.
    Considering Wireless Sensor Networks (WSNs) usage in sensitive applications, providing secure communication between the sensor nodes is of utmost importance. The key pre-distribution technique allows the sensor nodes to encrypt the messages employing the secret key to uphold the network security. Having limited computational powers and storage capacity are the constraints of sensor nodes. In this work, Combinatorial Design (CD) is employed to propose a deterministic scheme for key pre-distribution in WSNs wherein keyrings are generated from a given keypool. The network region is divided into many same-sized cells with regular sensor nodes and cell leaders deployed in each cell. The cell leaders possess higher resource and computational capabilities than the regular sensor nodes and thus are used for communication between cells. Whenever the regular sensor nodes need to establish communication links with other regular sensor nodes in the same cell, they can do so directly using the common secret key. The key pre-distribution scheme proposed for cell leaders is highly scalable. A detailed study of the scalability, the resiliency of the proposed scheme is also presented. The resiliency accomplished is comparable to other existing schemes. Still, at the same time, the given scheme provides full connectivity, high scalability without a significant increase in the storage overhead of the sensor nodes. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
