In the present scenario, numbers of vehicles are increasing day by day. People tend to apply brakes even in cases where it can be avoided. In highly congested roads, cases of drivers applying brake for every few metres of travel are no longer few and far between. With drivers competing for each and every inch of space available, accidents on the roads are(More)
In this paper, analysis of a dual-band filter using hairpin resonator is presented. By geometrical modifications of a hairpin resonator, bands stop and band pass characteristics are observed in the frequency spectrum. The variations of the geometrical parameters have been studied in detail and optimized for best filter performance.
Broadcast transmissions are currently finding extensive applications in vehicular ad-hoc networks, albeit primarily in the research phase. Given the importance of knowing the updated network details of each node in the network, and also considering the fact that the delay in transmission of messages is a crucial factor in collision avoidance, it is(More)
Broadcast transmissions are currently finding extensive applications in vehicular ad hoc networks, albeit primarily in the research phase. Given the importance of knowing the updated network details of every node in the network, it is required to have a thorough understanding of the behavior of the broadcast scheme. In this paper, we study the performance(More)
In this paper, a compact on chip band stop filter (BSF) using open loop resonator (OLR) integrated on silicon substrate is proposed. The BSF can be fabricated using the CMOS process without any additional steps thus making the filter cost effective in fabrication. The effect of additional layers in the filter characteristics is also presented. The proposed(More)
Broadcasting is envisioned to be a vital technology that will govern the behavior and analysis of vehicular networks. Since the topology of VANETs is subject to rapid changes, an efficient utilization of the broadcasting technology can easily help in conveying the location information of the vehicles as well as for the purpose of avoiding accidents.
