Abstract

Many of today’s applications have not been designed to be used in mobile environments. In order to build mobility in these applications there is a need to compromise in higher delay, higher error rate, and lower bandwidth. The customers not only need mobility but also quality. It is a great challenge for the service providers to offer Quality of Service (QoS). The QoS parameters are divided into two categories such as Qualitative QoS parameters (reliability,security,manageability, etc.) and Quantitative QoS parameters (bandwidth,delay, jitter, etc). The requirements of the above parameters will vary from one application to another application. In this paper, we would like to propose a QoS technique to store the actual QoS requirements of data transfer and to evaluate the performance of data transfer with respect to reliability. Certainly, the outcome of this paper will help to compare the expected QoS requirements with the actual QoS requirements, to understand performance degradation and to identify the parameters responsible for reliability problem.

Abstract

Objectives: To propose a new Data Dissemination Technique that intelligently works for finding the Best forwarding node. By using this forwarding Technique, the effective utilization of Bandwidth is achieved. Methods/Analysis: The Link Expiration Time and the Distance Rate is calculated between two vehicles within a Transmission Range. Node having the minimum Link Expiration Time is chosen as the next forwarder. Findings: Number of Redundant Transmission is reduced and the Bandwidth is efficiently utilized in Vehicular Ad hoc NETworks (VANETs). Conclusion/Application: This paper proposes an Intelligent Broadcasting Technique which involves selecting best Forwarder node. Thus it reduces the number of redundant transmission and utilizes the Bandwidth efficiently.

Abstract

Objectives: To propose a Dynamic Backbone based Broadcast Technique for sending the safety alert. By using this Technique, the effective utilization of Bandwidth is achieved. Methods/Analysis: A competitive score is calculated based on the Distance and Direction of vehicles. Vehicle’s having more score is elected to relay the safety alert. Findings: Number of Redundant Transmission is reduced and the Bandwidth is efficiently utilized in Vehicular Ad hoc NETworks (VANETs). Conclusion/Application: This paper proposes a Dynamic Backbone based BroadCAST technique (DBCAST) which chooses a Backbone node with the help of a Competitive score. Because, this technique uses Backbone selection which is carried out till the end of the transmission range, it reduces the Bandwidth utilised when comparing with the relaying technique.
