The BROGO algorithm has been recently presented for Leader Election in Wireless Sensor and IoT Networks, where after finding a spanning tree of a network, each leaf will route a message through its branch to the root in order to determine the leader in that branch. The root will then elect the global leader among the received branch leaders. The main drawback of this algorithm is a possible failure...
Cloud-based platforms for handling Internet-of-Things data can reduce the energy consumption of various ICT modules (e.g., data centers, networking equipment, battery-equipped devices) by applying appropriate system configurations. However, this is currently prevented by the higher prioritization of other goals, the complexity or unawareness of the synergies between system configurations and energy...
This paper focus on multi hop mobility management in WSN ad hoc Network using DVS algorithm for minimum energy consumption. To improve cross layer collaborative in wireless sensor network as well as to improve processing capacity according requirement. In WSN, senor do not only process information at application layer but also synchronize their communication. Using our propose architecture containing...
The introduction of mobile sink to wireless sensor networks (WSNs) can effectively address the hot-spot problem. However, as the sink moves in the sensing area, its location information needs to be broadcasted periodically to ensure network connectivity. This additional location update process will increase communication cost in each sensor node. To deal with this problem, this paper proposes a Square-Based...
Cognitive radio sensor network (CRSN) is an emerging sensor networking paradigm that aims to incorporate opportunistic spectrum access capability to the wireless sensor networks. Since sensor nodes are energy-constrained devices, design of efficient spectrum sensing schemes is imperative for the implementation of CRSNs. In order to address this need, a cooperative spectrum sensing scheme (CSS), specifically...
Recent advances of hardware and integrated chip have made the body-implanted medical device reality. In this paper, a chronic disease management system with implanted devices based on Wireless Sensor Networks (WSN) was proposed for people with chronic illnesses. We first described the architecture of the chronic disease management system. Then through analyzing the system architecture, we explained...
A wireless sensor network can be divided into several clusters. Each cluster has a number of sensors nodes and one of the nodes is elected as the coordinator, termed as head. The head is responsible for not the general mission but also collecting the sensed data of other nodes and routing to the sink. Accordingly, the energy-consumption is higher than other nodes. Therefore, the head selection will...
Clustering is a good method to increase WSN lifetime and particularly for smart environment. In this paper, we present fuzzy position based routing for clustered sensor network. It is very useful for the smart environment applications of wireless sensor network without GPS support. The destinations could be located with ambiguous position vectors, and the long time and energy consumption of requesting/replying...
Transmission Control Protocol (TCP) was considered unsuitable for Low power and Lossy Networks (LLNs) due to the characteristics LLN devices (low computing power, strong energy constraint, etc.) and to the absence of IP layer on the network layer. Recently, the IPv6 over Low power Wireless Personal Area Networks (6LoWPANs) has been introduced as an adaptation layer for IPv6 over LLNs. Thanks to the...
Wireless sensor nodes operating in unlicensed bands can exploit frequency agility in order to mitigate, through dynamic spectrum access, the effects of interference induced by collocated networks. With this respect sensor devices can select the frequency band used for their communications in an opportunistic manner: this however requires spectrum sensing and consumes precious energy when more and...
In wireless sensor networks, clustering algorithm prolongs works' lifetime drastically. In a cluster, because the distances are different between member nodes and head node, the energy consumption of member nodes will become unbalanced when they transmit message to the head node directly. The EBCA (energy balanced consumption algorithm) is proposed for the problem. In EBCA, member nodes are divided...
In this paper, a novel Uneven Cirque energy-balance Clustering Routing for sensor networks (UCCR) was proposed. UCCR import energy forecasting mechanism, according to the residual energy of node to determine when to re-cluster. Cluster head is chosen based on the residual energy and the relative position. Multi-hop data routing was formed in inter-cluster, routing to build not only consider the energy...
The application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes. In order to reduce the entire energy consumption of the WSN, a promising approach is to design light clustering algorithms. LEACH is such a well-known clustering algorithm that was designed to distribute the energy consumption to nodes in the WSN evenly. LEACH is characterized by its attractive...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
