Abstract:
Cotton has profound significance in the textile industry due to its versatility, comfort and ease of care. But the main problem with conventional cotton farming is that it uses more water. These issues are made more difficult by conventional irrigation methods, such as drip irrigation. To address this problem researchers are using traditional farming techniques with advanced wireless sensor network (WSN) protocols to resolve catastrophic issues, such as pipe bursts or blocked emitters which are detected early to save the water. This paper introduces efficient WSN architecture using priority-ba

Abstract:
In this paper, a multi-strategy routing protocol, reactive-greedy-face (RGF), is proposed based on the advantages of reactive forwarding, greedy forwarding, and projected face forwarding strategies. This protocol improves and unites the strategies through a reasonable selection and switching mechanism to make up for the deficiencies of the existing three-dimensional routing protocols in the flight self-assembly network and improve the rapid recovery of packet forwarding after topology changes. The simulation validation shows that this routing protocol can be used to recover packets after a top

Abstract:
According to characteristics that the vehicles move fast and topology changes quickly in Vehicular Ad hoc Networks (VANETs), a novel routing protocol GMGP based on the location is proposed for VANETs. Predicting the changes of the neighboring nodes positions and using greedy forwarding mechanism forward packet, and using a movement perimeter forwarding algorithm to select the next reliable hop node on the basis of direction and velocity of the mobile nodes when the greedy forwarding fails, it improves the reliability of routing.

Abstract:
In recent years, vehicular communication systems have taken an important place in Intelligent Transport Systems (ITS). These systems are designed on self-organizing networks, known as Vehicular Ad hoc NETworks (VANETs). Their objective is to struggle against road safety problems and road traffic congestion by integrating information and communication technologies in road infrastructures and vehicles. VANET differs from other types of ad hoc networks by high mobility and very dynamic topology. Consequently, the design of an efficient VANET routing protocol becomes a challenging task. Many routi

Abstract:
Compared with traditional GPCR, there are three differences in the new GPCR-D: 1) GPCR-D is a topology and position based routing protocol. 2) It can detect dynamically the network density and establish the local areas with high node density, where vehicles speed is limited and topology changes slowly. Therefore, we adopt shortest path algorithm aimed at delivering packets speedily. While outside the local areas, topology changes rapidly, so greedy forwarding is used to avoid restoring and maintaining links frequently. Thus GPCR-D makes full use of their respective advantages. 3) The repair st

Abstract:
Intelligent vehicular networks can not only connect various smart terminals to manned or unmanned vehicles but also to roads and people’s hands. In order to support diverse vehicle-to-everything (V2X) applications in dynamic, intelligent vehicular networks, efficient and flexible routing is fundamental but challenging. Aimed to eliminate routing voids in traditional Euclidean geographic greedy routing strategies, we propose a hyperbolic-embedding-aided geographic routing strategy (HGR) in this paper.

Abstract:
This article describes how a vehicular ad-hoc network (VANET) is an infrastructureless network in which vehicles are connected without wires. Routing in VANET is challenging nowadays due to increased number of a vehicle, the high mobility of nodes, dynamically changing topology and highly partitioned network, so the challenges on the roads are also increased like the road congestion, the safety problem, speed, etc. Various protocol designs have been suggested by various authors to search and forward packets to the destination node. These various algorithms use different schemes like greedy for

Purpose The purpose of this paper is to give an insight in to the routing protocols in Vehicular ad hoc Network (VANET). In this direction, for the efficient data dissemination in VANETs, a street-based forwarding protocol (SBFP) has been proposed. Design/methodology/approach The interferences among different street segments are considered and a unique street-based forwarding concept is introduced to reduce the local maximum problem. In this protocol, the greedy forwarding concept along with the broadcasting mechanism and suppression technique is implemented to minimize the overhead created in
