Before inception of Internet of Things (IoT), personal computers and laptop were used to handle daily tasks of individuals like mail surfing, access to bank portal, observing current temperature, among others. Nowadays, IoT-enabled smart devices like smart mobile phones, PDAs, and tablets are being used by them for such tasks due to rapid growth in IoT. Smart homes have been widely accepted by individuals...
In the present arena, wildlife and forest departments are facing the problem of movement of animals from forest area to residential area. The number of trees has reduced drastically from the forest that creates an unhealthy environment for animals to survive in the forest. This paper proposes a system we call GATA for tracking and alarming for the protection of Wildlife Animals. GATA combined Wireless...
Message exchange among vehicles is an integral part of communication in smart cities. Messages are exchanged to inform the other vehicles about emergency situations such as-safety alerts, and location privacy. Due to the usage of an insecure wireless medium, malicious activities in vehicles, i.e., illegal use of the false messages, can astray other vehicles. Security in communication among the vehicles...
Next Generation Wireless Networks (NGWNs) are expected to be heterogeneous, which integrate different Radio Access Technologies (RATs) such as 3GPP's Long Term Evolution (LTE) and Wireless Local Area Networks (WLANs) where a transmission is supported if the signal-to-interference-plus-noise ratio (SINR) at the receiver is greater than some threshold. In this paper, we analyze the interference in heterogeneous...
The vital trend inside wireless networks is the heterogeneity of access technology. Vertical handover management is one of key challenges in such environment to ensure seamless mobility and service continuity especially in the case of network mobility. To deal with some of these challenges, numerous efforts were made in the context of standards and scientific research to perform the vertical handover...
Vertical handover management is one of key challenges in heterogeneous network environment. In order to address some of these challenges, an IEEE 802.21 Media Independent Handover framework is standardized. The main objective of this standard is to provide a general interface for the handover by abstracting the link layer intelligence to higher layers. However, there still exist a number of limitations...
Radio over fiber (RoF) technology is considered as an energy and cost-effective solution to cover the users' rapidly increasing demands for bandwidth and mobility. However, integration of a wireless and an optical network into a hybrid one needs the design of new protocols. In this work, a novel MAC protocol based on the MultiPoint Control Protocol (MPCP) is proposed. The network's decision center...
- This paper proposes a novel multipath routing protocol for MANETs. The proposed protocol is a variant of the single path AODV routing protocol. The proposed multipath routing protocol establishes node-disjoint paths that have the lowest delays based on the interaction of many factors from different layers. Other delay aware MANETs routing protocols don't consider the projected contribution of the...
In this paper we present a novel algorithm, implemented in a wireless sensor network environment, for the study of fire in a natural environment. This algorithm can offer two kinds of information: the risk of a fire and, in case of an active fire, the propagation direction of the flames and their velocity. This information is useful for fire rangers in order to obtain escape ways and determine strategies...
This paper proposes a QoS multipath routing protocol (QMRP) for MANETs based on the single path AODV routing protocol. QMRP establishes node-disjoint paths that experience the lowest delay. Other delay-aware routing protocols do not factor in the projected contribution of the node requesting a route in the total network load. The implication is that the end-to-end (E2E) delay obtained through RREQ...
Recent technological advancements in the field of nanotechnology have increased the computation power of the wireless nodes while adhering to the energy constraints. This has made the use of the Wireless Sensor Networks (WSNs), more widespread, used in applications such as area monitoring, industrial monitoring, vehicle detection or military monitoring. Sensor nodes have made it possible to collect...
The use of Wireless Sensor Networks (WSN) is anticipated to bring lot of changes in data gathering, processing and dissemination for different environments and applications. Energy consumption is the most crucial design issue in WSN. In order to solve the issue and prolong the network lifetime, energy resources of each node in WSN need to be effectively managed. With respect to energy efficiency,...
Major constraints to be kept in mind while designing a routing protocol for ad hoc networks are battery power consumption, congestion control, time delay and the transmission range of the nodes. In this paper, we aim to develop an energy efficient and angular routing protocol, named Efficient Reactive and Angular - Optimized Link State Routing (ERA-OLSR). ERA-OLSR is an enhanced protocol designed...
The interconnection of mobile devices in urban environments such as shopping malls can open up a lot of vistas for collaboration and content-based services. This will require setting up of a network in an urban environment which not only provides the necessary services to the user, but also ensures that the network is energy efficient. In this paper, we propose an energy efficient dynamic routing...
In VANETs, security is of prime concern. A successful attack by an adversary might have disastrous effects leading to loss of life. At times an adversary may perform event modification, false event generation, data aggregation and data dropping. To overcome these we present a robust algorithm VSRP (Vehicular Security through Reputation and Plausibility checks) to employ security in VANETs. The algorithm...
IEEE 802.16 (WiMAX) constitutes one of the most promising broadband access technologies for high-capacity and high-distance wireless access networks, supporting user mobility. The contribution of this paper is twofold. Firstly, a novel mapping scheme for IEEE 802.16 Mobile standard is introduced, applying horizon mapping. Secondly, an efficient adaptive prediction-based scheme is devised, which is...
The past few years have observed vehicular networks becoming increasingly important in order to exchange information between stationary or moving vehicles. The information exchanged can range from warning messages in case of accidents that have occurred on the road and traffic jams to guiding the vehicles about the most efficient path to reach their destination. The biggest challenge, a vehicular...
