    An index coded approach for reducing number of broadcasts in vehicular networks
    (Institute of Electrical and Electronics Engineers Inc., 2017) Patil, A.; Shekar, N.; Shet, N.S.V.
    Vehicular network standard demands a short range reliable vehicle-to-vehicle (V2V) communication with high mobility, also increasing amount of downloaded data in short encounters. Satisfying demands of clients with minimum number of transmissions using index coding has proven notable significance in wireless ad-hoc networks. The proper encoding at the server with side information leads to simultaneous satisfaction of clients with reduced amount of broadcasts. MERLIN (Maximum Expected download over Random LINks) is one of the fundamental protocols developed for optimizing downloads in vehicular networks over random encounter durations [1]. In this paper, we present I-MERLIN (Index coding based MERLIN) protocol and analyze its performance over MERLIN. We show that same amount of data can be downloaded from server in reduced number of transmissions, for single server multiple clients scenario. We also show that, I-MERLIN works well to satisfy multiple clients in minimum number of requests, which can be applicable for real road scenarios. © 2017 IEEE.

    Transmit Data Rate Control Based Decentralized Congestion Control Mechanism for VANETs
    (Institute of Electrical and Electronics Engineers Inc., 2019) Patil, A.; Deeksha, M.; Shekar, N.; Shet, N.S.V.; Kulkarni, M.
    Vehicular Ad Hoc Networking (VANET)technology is becoming prominent in this era. It is defined to improve on-road conditions and provide safety and different entertainment applications to end users in orderly and efficient manner. The idea of making everything connected in Internet of things (IoT)has evolved as a promising networking system and VANETs are one of the components of it. In this paper, we present a multistate active transmit data rate control based decentralized congestion control mechanism. The real world scenario generated from SUMO is considered for simulation. Simulation results show that, data rate control mechanism performs better over transmit power control and without adaptation mechanisms. © 2019 IEEE.
