Underwater Acoustic Sensor Network (UASNs) are deployed in sea for exploration of underwater hidden natural resources. There are certain research issues regarding routing and MAC protocol in the deployment of UASNs. The main challenges may be inefficient network life time, low throughput, high propagation delay and unbalance energy consumption. In order to improve the results of the basic parameters...
The increasing number of autonomous and semi-autonomous vehicles on the road leads to an increasing need for external vehicle communication, in particular through emerging vehicular ad hoc networks also known as VANETs. This technology has the ability to facilitate intelligent transportation applications, comfort and other required services for self-driving vehicles. However, suitable routing protocols...
This paper applies the theory of Evolutionary Game to QoS routing algorithm for wireless mesh networks which can not only improve the performance of traditional QoS routing protocols but also be able to reduce the cost of the routing algorithm.
Wireless sensor network is composed of many wireless sensor nodes with the same or different functions. A typical sensor node consists of four parts: sensor unit, information processing unit, wireless communication unit and energy supply unit. In this paper, the existing ant colony algorithm is analyzed, and an improved ant colony optimization algorithm is proposed. The paper presents design of routing...
The growing of the internet use is proportional with the growing of IP address needs, but the increasing of the IP use is not equal with the number of available IPv4. Then, IPv6 was developed as a solution to overcome the limited amount of IPv4 address. Readiness of various aspects ranging from infrastructure to a service provider is required to implement IPv6. In order to improve the quality of IPv6...
The design of routing protocol in mobile social delay tolerant networks is a tricky issue due to lack of stable end-to-end path, frequent link disconnection and changeable network topology. This paper proposes a novel routing algorithm based on dynamic topological potential and social relationship (DTPSR) between nodes for mobile social delay tolerant networks. In DTPSR, we define three metrics to...
A group of mobile nodes with limited capabilities sparsed in different clusters forms the backbone of Mobile Ad-Hoc Networks (MANET). In such situations, the requirements (mobility, performance, security, trust and timing constraints) vary with change in context, time, and geographic location of deployment. This leads to various performance and security challenges which necessitates a trade-off between...
Byzantine attacks are constant threats in many applications such as disaster management, and battlefield applications. In this paper, we introduce a monitoring scheme in the link state routing protocol to secure the packets' route against Byzantine attacks. The goal of our proposed scheme is to guarantee communication among connected benign nodes in the network. Specifically, each node monitors the...
In order to verify the application effect of MANET Routing Protocol in vehicular ad hoc network, the table driven routing priors DSDV, OLSR and on-demand routing reactive AODV are used to verify the results. In this paper, the simulation platform is built by NS3 and SUMO, and the performance of MANET is verified by comparing the network performance parameters, such as throughput, packet delivery rate...
A mobile ad hoc network is a wireless network of mobile devices that communicate with one another without any fixed network infrastructure. Existing mobile ad hoc networks are either based on IEEE 802.11 a or b standard. Both standards provide limited bandwidth and therefore are not suitable for data intensive applications such as automated video surveillance. Wi-Fi Direct is a new technology that...
Wireless body area networks (WBANs) have risen great concern among the society in the fields such as health care and disease control and prevention. However, the radio frequency radiation produced by frequent communication and utilization of nodes leads to temperature rise, which does great harm to human bodies. For that reason, the thermal-aware technology is of great value in research, which also...
Space self-organizing network is a kind of space communication network, which applies self-organizing network to deep space. Future space exploration demands a self-organizing network that will be able to connect spacecrafts with one another and in turn with Earth's terrestrial Internet and hence efficiently transfer data back and forth. The coverage area of the space self-organizing network is large,...
A number of applications of Intelligent Transportation Systems (ITS) rely on multi-hop broadcasting in order to disseminate useful traffic information to other vehicles located in a geographical area. However, the conventional broadcast mechanism may lead to the so-called broadcast storm problem, which causes a high level of contention, collision, and congestion due to an excessive number of broadcast...
Nowadays Wireless sensor network achieve much attention due to its several real time applications like in military works, fire detection, temperature sensing etc. Sensor nodes are randomly distributed in the network and have limited energy. Due to this energy constraint, efficient routing protocol comes into picture. A sensor node senses the environment and generated the data. It sends the data to...
Efficient power use is the fundamental to think about tried and true operation of wireless or remote sensor frameworks. This applies correspondingly to direct or linear sensor masterminds as they create when sensors are sent along linear frameworks such as pipelines. In this work, a innovative approach to manage imperativeness capable controlling to a dual base station or control center in a straight...
This paper is concerned with the design of routing protocol capable of congestion mitigation for drone-cells communication networks where drone-cells remain stationary in the sky as relays. All of the (distance or hop-count based) existing routing protocols can perform well when the network is lightly loaded. Once the network is heavily loaded, a large number of packets might be backlogged in queues...
In this paper we consider the selection and deployment of MANET protocol to efficiently route the traffic and communicate in Tactical Battle Area (TBA). Tactical Wireless Communication Network (TWCN) provides connectivity between Wide Area System (WAS) of TWCN nodes, forming a backbone transmission network. TWCN is for TBA that consists of Network Centric Systems. These entities impose routing challenges...
Low Energy Adaptive Clustering Hierarchy (LEACH) protocol is considered as one of the most important protocols that are frequently used in the Wireless Sensor Network (WSN). Many protocols were developed to modify and improve the LEACH protocol. The multi-hop technique (MHT-LEACH) is one of these protocols, which appeared to improve the performance of the LEACH protocol. In this paper, an improved...
Increased life expectancy and rising medical expenses impose big issues for proper health care and monitoring. Wireless Body Area Networks (WBANs), a group of small sensor nodes attached inside, on or around the human body, were introduced to meet this requirement. On body topology disconnections occur due to ultra short range radio links, unpredictable RF attenuation and human postural body movements...
The development of routing protocols for underwater sensor networks (UWSNs) faces with different challenges, the most notable of which is perhaps how to deal with a void communication area. Over the past few years, some underwater protocols equipped with the void-handling techniques have been proposed to address this issue. The majority of them, however, are unable to detect and bypass the trapped...
