VANET: Expected Delay Analysis for Location Aided Routing (LAR) Protocol

Submitted in April, 2016; Accepted in July, 2016 Abstract – The Vehicular Ad-hoc Network (VANET) is a networking technology uses to create wireless network using mobile vehicles. In this network, the mobile vehicles work as intermediate node to transmit data packets over the wireless network and mobile nodes are free to move from one network to other network. All nodes in VANETs are highly movable and their movements area and direction to be restricted within a predefined geographical areas. All nodes in VANETs nodes must has to follow certain conditions such as their speed to be restricted by standard speed limit, patterns of the road, and traffic conditions. Due to high speed of nodes in the network, links may breaks frequently due to this failure in data delivery occurs in the network. Routing of data packet in the VANETs are more challenging task due to highly dynamic natures. Performance of the VANET depends upon the selection of the suitable next-hop nodes for further transmission in the network. Due to highly movable vehicular nodes, the link may break very frequently caused network delay; therefore, it is important to select the appropriate next-hop forwarding node to complete the data transmission. In this paper, we have computed the node distribution at the border area, expected one hop distance and expected delay using one-hop distance between first two nodes. Further, we have analyzed the numerical results using MATLAB.
