Ad-hoc On-demand Distance Vector (AODV) provides scalable and effective solution for packet routing in mobile wireless ad hoc networks, however, the path generated by this protocol may derivate far from optimal because of inconsideration of node power ,load unbalance and link state,resulting in energy consumption of each nods is imbalanced and reduce the lifetime of whole networks. Based on the...

MANETs are ad hoc multi hop networks, formed of mobile battery chargeable devices and commonly used in emergency situations. With its dynamic topology and limited energy level they often come across with link breaks. This paper analyzes how energy consumption of the mobile devices and density of mobile nodes affects the performance of MANET. AODV and AOMDV are reactive routing protocols used in...

IoV is the latest application of VANET and alliance Internet IoT. With rapid progress in technology, people are searching for a traffic environment where they would have maximum collaboration with their surroundings which comprise other vehicles. It has become necessity to find such we less congestion, minimum chances vehicular collision, communication delay, fewer errors, greater message deliv...

Adhoc on demand distance vector routing protocol(AODV) is specially designed for mobile adhoc networks with reduced overhead using Expanding Ring Search technique. But energy consumption should also be considered in MANET due to battery constrain of the nodes. In this paper, we choose an energy efficient route discovery process for AODV based on Expanding Ring Search(ERS). We want to saves ener...

In Vehicular Ad Hoc Networks (VANETs), the node mobility leads to network topology changed frequently. Due to the vehicle movement, the limited wireless resources and channel fading, the routing protocols in Mobile Ad Hoc Networks MANETs are not suitable for VANETs. In this paper we propose a new multipath route protocol based on Ad hoc On-Demand Distance Vector Routing (AODV) for adapting VANE...

The communications inside MANETs usually show frequent disruptions due to changes in topology and the condition of having a shared physical channel. It is necessary to implement a mechanism to maintain connectivity and ensure Quality of Service (QoS). In this paper we introduce a route recovery mechanism for a QoS routing protocol called AQA-AODV (Adaptive QoS-Aware AODV) which is an extension ...

—Ad hoc On-demand Distance Vector (AODV) routing protocol has been widely applied in Wireless Ad-hoc Sensor Networks (WASN). Link breaks often occur in WASN due to the mobility of nodes or other reasons. Only after a link break detected, the route repair scheme in AODV will be initiated to keep the connectivity of network. In this paper, we propose an enhanced Preemptive Local Repairing Mechan...

Present Internet has been developed approximately for past forty five years. Nowadays many network researchers are involved in wireless communications. Wireless networks allow hosts and routers to roam without the constraints of wired connections. Therefore, the network topology can be dynamic and unpredictable. Traditional routing protocols used for wired networks cannot be directly applied to...

This paper presents a framework for node distribution with respect to density, network connectivity and communication time. Using NS2, we evaluate and compare performance of three routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) both in MANETs (IEEE 802.11) and VANETs (IEEE 802.11p). We further enhanced these protocols by c...

In mobile ad hoc wireless networks (MANETs), traditional protocol like AODV performs well for low mobility of nodes but not for high node mobility. So, it becomes important to consider mobility factor during the path selection procedure of routing protocol. Here, a fuzzy logic mobility based protocol (FLMAODV) that considers the mobility factor is proposed. Due to the consideration of mobility ...
