To satisfy requirements from various applications in the smart grid, transmitting data robustly and reliably has become one of the most crucial tasks. However, existing routing protocols like CTP, LEACH, HWMP cannot be directly applied to the smart grid system. In this paper, we propose RH-HWMP, which provides robust data transmission for the neighbor area network (NAN) in the smart grid. The main...
Our objective in this paper is to improve the communications performance for IoT applications by proposing a new solution called IC-IoT (Improving Communication for IoT). The principle used is the exploitation of three existing communication protocol by incorporating some mechanisms to consider the different parameters which can cause the data loses. A probabilistic approach is used to know the impact...
Since its definition, RPL (the IPv6 Routing Protocol for Low-Power and Lossy Networks) has been emerging as the standard protocol for routing in Internet of Things (IoT) solutions. RPL is a proactive routing protocol that performs the process of route creation based on Objective Functions (OFs). The OFs are responsible for defining rules and constraints to select the best paths considering different...
Many broadcast protocols have been proposed in Vehicular ad-hoc Network (VANET) for safety applications and traffic efficiency. GeoBroadcast, which the sender sends information to the geographical area, has been standardized by the ETSI Technical Committee ITS. The routing protocol is a key technology satisfying communication requests of high reliability, low delay and universality for GeoBroadcast...
Efficient routing is one of the key challenges for next generation vehicular networks for providing fast and reliable communication in a smart city context. Various routing protocols have been proposed for determining optimal routing paths in highly dynamic topologies. However, it is the dilemma of those kinds of networks that good paths are used intensively, resulting in congestion and path quality...
Geographic routing protocols establish scalable and robust routes for multi-hop trsdansmission in wireless mobile ad-hoc networks, where accurate location information of the mobile nodes is needed. Aiming to alleviate the influence of location errors, existing works focus on modifying routing protocols through modeling the error sources and mobility prediction. In this paper, we propose a cooperative...
Maintaining the reliability of Next Hop selection (NHS) in Inter-Vehicle Communication (IVC) technology has witnessed significant attention among researchers nowadays. The reason is because reliable selection of the next hop could improve the performance of geographic routing protocols, which is a major goal of Intelligent Transportation Systems (ITS) applications. This paper provides a qualitative...
The article aimed at offering new ways of routing in networks with the DTN architecture, which allows using the most optimal routes for determining the routes depending on various conditions. To achieve these goals, it is necessary to analyze the available developments in this field with the subsequent identification of advantages and disadvantages. An attempt to realize advantages with a minimum...
Opportunistic routing (OR) has emerged as a promising paradigm to the design of routing protocols for underwater sensor networks (UWSNs). However, despite of its advantages, it introduces a critical problem that has been neglected until now: the immutable transmission priority level of the next-hop forwarding nodes. This characteristic can lead to an overuse of a unique node (or a few of them), quickly...
Wireless sensor network(WSN) contains a number of sensor nodes distributed in the sensor field. Sensor nodes gather information from the environment, process them and then transmit data to the sink node. To send data from the source node to sink node require efficient routing algorithm. This routing algorithm plays important role in WSN is to finding a reliable path for a data transmission in the...
This paper addresses the issue of reliable data delivery in highly dynamic Mobile Ad-hoc Networks (MANETs). Most existing MANET routing protocols are susceptible to data delivery in reliable and timely manner. To counter this problem, Position-based Greedy Forwarding protocol (PGF), a novel GR protocol which takes advantage of greedy forwarding and opportunistic routing is proposed. In PGF, the best...
Many common DTN routing protocols are replication-based, which have relatively good performance in terms of message delivery ratio but high overhead, and leave the issue of garbage collection open. In this paper, we propose Named Data Distance Routing (NDDR), a named data based DTN routing approach which makes routing decisions for named data based on topological distance information. This helps to...
Mobile Ad hoc Network has a wide range of applications in military and civilian domains. It is generally assumed that the nodes are trustworthy and cooperative in routing protocols of MANETs viz. AODV, DSR etc. This assumption makes wireless ad hoc network more prone to interception and manipulation which further open possibilities of various types of Denial of Service (DoS) attacks. In order to mitigate...
In deep waters, both the natural acoustic systems (such as marine mammals) and artificial acoustic systems (like underwater sensor networks (UWSNs) and sonar users) use acoustic signals for communication, echolocation, sensing, and detection. This makes the channel spectrum, heavily shared by UWSNs posing several salient features such as narrow bandwidth, long propagation delay, and high packet loss...
Advancement of medical science brings together new trend of proactive health care which gives rise to the era of Wireless Body Area Networks (WBAN). A number of issues including energy efficiency, reliability, optimal use of network bandwidth need to be considered for designing any multi-hop communication protocol for WBANs. Energy consumption depends on many factors like amount and frequency of forwarding...
Intelligent Transport Systems (ITS) and the open-ended research in the field of vehicular communication attempts to deal with the road traffic problems. In Vehicular Ad-Hoc Networks (VANETs), vehicles are moving faster in comparison with Mobile Ad-hoc Networks (MANETs). Furthermore, in urban VANETs, vehicles are constrained by the layout of the roads and buildings, which causes shadowing effects....

While mobile ad hoc networks have become a mature & globally adopted technology due to its wide range of applications. Such environment has some basic differences in comparison to wired networks. Due to these little differences the MANETs are more prone to interception and manipulation. This further opens possibilities of insecure routing. For the efficient and secure delivery of data CRCMD&R...
In ad hoc networks, terminals form a network with decentralized and self-organizing manners. Although this can surely extend its potentials, it also suffers from unstable and unreliable communication environments. As concerns this, a broadcast-based routing protocol called opportunistic routing (OR) has been proposed. ORs do not establish any specific route from a source terminal to a destination...
The design of path allegiance metric (PAM) based routing protocol leverages upon a trust management framework proposed in our earlier works. The PAM routing protocol strives to provide data plane security in mobile ad hoc network and its working is based upon the belief, disbelief and uncertainty components of the trust management framework which assigns a trust metric based upon the packet forwarding...
