“…The intersection-based geographical routing protocol (IGRP) [8] is also an intersection-based geographical routing protocol which has some similar mechanisms with our work. It chooses the path that maximizes connectivity probability while satisfying the QoS constraints regarding hop count, BER, and end-to-end delay.…”

Vehicular ad hoc networks (VANETs) are going to be an important communication infrastructure in our moving life. The design of routing protocols in VANETs is a significant and necessary issue for supporting VANET-based applications. However, due to high mobility, frequent link disconnection, and uneven distribution of vehicles, it becomes quite challenging to establish a robust route for delivering packets. This paper presents a connectivity-aware intersectionbased routing (CAIR) protocol to address these problems by selecting an optimal route with higher probability of connectivity and lower experienced delay; then, geographical forwarding based on position prediction is used to transfer packets between any two intersections along the route. Simulation results show that the proposed protocol outperforms existing routing protocols in terms of data delivery ratio and average transmission delay in typical urban scenarios.

“…One of the simple but efficient methods to improve the path stability is to find the next hop with the longest link duration (or the most stable connectivity) [11][12][13][14][15]. A Receive On Most Stable Group-Path (ROMSGP) scheme [11] has been designed to choose the most stable path with the longest link expiration time.…”

Multihop data delivery between vehicles is an important technique to support the implementation of vehicular ad hoc networks (VANETs). However, many inherent characteristics of VANETs (e.g., dynamic network topology) bring great challenges to the data delivery. In particular, dynamic topology and intermittent connectivity make it difficult to design an efficient and stable geographic routing protocol for different applications of VANETs. To solve this problem, the paper proposes an adaptive routing protocol based on QoS and vehicular density (ARP-QD) in urban VANETs environments. The basic idea is to find the best path for end-to-end data delivery, which can satisfy diverse QoS requirements by considering hop count and link duration simultaneously. To reduce the network overhead furthermore, ARP-QD adopts an adaptive neighbor discovery algorithm to obtain neighbors' information based on local vehicular density. In addition, a recovery strategy with carry-and-forward is utilized when the routing path is disrupted. Numerical simulations show that the proposed ARP-QD has higher delivery ratio than two prominent routing protocols in VANETs, without giving large compromise on delivery delay. The adaptivity of ARP-QD is also analyzed.

“…Destination location can be obtained via the pure ad hoc network or another network such as cellular or sensor networks which can affect protocols performance and communication cost. In the route selection process, protocols deploy different methods such as pure geographic, anchor-based [15,17,19], static information such as map [18] and bus routes [19], statistics information and real-time information [20].…”

“…vehicles in a VANET communicate with each other by sharing road condition and safety information, to enhance passenger and road safety and to effectively route traffic through dense urban areas [1].VANET is self-configuring network which consist of vehicles, elements of road side infrastructure ,sensors and pedestrian personal [2]. It can be easily deployed without relying on expensive network infrastructure.…”
