Cross Layer Optimization with QoS for Heterogeneous ad-hoc Network

Abstract

In this paper, different scenario-based network performance parameters with optimization for heterogeneous ad-hoc are reviewed, observed and analyzed. Emergency services, traffic congestion and safety issues in transportation system can be resolute by intelligent communication heuristic and transforming information between vehicles and transportation infrastructure. Dynamic behavior of topology, high mobility, congestion, scalability and self-organization makes it difficult and costly to implement in real time deployment. Under different scenarios and conditions performance of different routing protocols and network lifetime are observed in literature by different authors using different simulation tools. Road conditions, variable speed of vehicles, driver unpredictable behavior and obstacles influence the performance of different routing protocols. Mobility and packet size put a great impact on network lifetime. In this paper we analyzed the throughput and packet delivery ratio at different BSMs in three different scenarios one for urban city and two scenarios for routing protocol with varying speed of vehicle. Mobility and link awareness can enhance the network lifetime and other parameters like throughput, goodput and packet delivery ratio of vehicular ad hoc network observed under simulation.
